- Having issues with the throttle body on your S197 Mustang? Follow along as I learn from my own mistakes, actually troubleshooting my issue instead of throwing parts at it (I already did that).
This is the throttle body cleaner I use: amzn.to/3wmuByA
It seems to work great every time. I always seem to go through an entire can tho, so buy two.
Extremely helpful! Dealing with a similar issue and I believe this will help!
Excellent video! I learned a lot. Thank you for putting this video together.
Update: It’s been a few months now, a little over 3k miles. The issue never returned. The weather has now turned cold, so mileage will not accumulate until the salt trucks disappear in Spring. So-far, so-good.
Hello mark loved your video learned a lot about my mustang's throttlebody in the last 15 minutes lol
07 4.6 L Eddie Bauer Exploder. , I decided to Seafoam spray clean the intake through the Throttle body. The result I believe is I messed up the TPS , I already have a brand new Cardone throttle body as I have been restoring this truck being a gift from my late father in law . Saw another vid that says Cardone uses a first gen faulty TPS on their build , so I ordered the robust recommended replacement TPS . But the breakdown before this was related to buying the cheap Chinese parts from amazon , I bought a mass airflow sensor and a fuel rail pressure sensor for under $60, and after getting the best mpg since I had it almost factory new mpg, @140,000 , she would not start well or even idle, so $400.00 later for the same parts from the dealer , gut punch 🥊, hit me again !! One more time . That’s about right .... I put on those parts and boom 💥!! Back to normal again .... so yea now I’m in the position you were in , I’m still going to replace the TPS but , I will follow your calibration procedures if that does not do the trick , sea foam had me put the spray tube in and through the butter fly valve and and reconnect the air intake with Mass AF , and hold a 2,000 rpm while spraying .... we didn’t get through half the bottle before the self inflicted breakdown occurred . Did this some cleaning two years ago without incident ... so I def think the TPS has failed .
But I did upgrade factory exhaust with the mandrel bent Magnaflow Exh from the manifolds back ( eliminates the resonator) wow she sounds like a a Mustang now and the power I have gained puts a grin on my face every time I get to take her for a spin!! Makes me feel like a teenager again !!! Saving up for new heads and I have been watching a lot of Tranny rebuild vids for the 6R60 .... saving for a rebuild kit , if clearing the TCM tables does not provide smoother shifting ... well adding that to the queue ... thanks for the video !! Keep Cruzin !!! FJB. TrumpWon2Q2Q
Thank you for putting this video together. I got my 07 back up and running !
Great video and very informative. Just thought I would add to this , in case someone else was having problems after trying everything else . The only other problem if this did not repair, your issue …could be the accelerator pedal position sensor. The unit plugs in , and has two failsafe circuits On board inside your car pedal. The computer monitors the (2) potentiometer circuits for redundance. I watched a lot of videos online since I have a 2007 mustang. The wrench light and the limp mode Can be caused by multiple sensors in your throttle system. It takes an oscilloscope to see a quick dip A bit least one second… in voltage on one of the two circuits… that can’t be picked up by most handheld units at a dealership. It basically has electrical contacts that sweep two separate potentiometer Circuits. You could have a dead spot or a complete malfunction. It can sporadically happen, causing the wrench light to come on. It’s seeing (2) unexpected reading simultaneously. The ECM throws up the wrench and goes into limp mode for safety, thinking the car could be over accelerating, and chooses to stay in idle with no acceleration response. The TPS and the accelerator position sensor….. ALL communicate with the throttlebody and this is also something to check. I ordered a Complete replacement Accelerator pedal assembly …just plug in the connector Going to the ECM. All the parts stores sell this complete assembly and they are definitely low in stock because this is a big problem also.
@@kellymeade4587I had this issue a year ago and replaced my throttle as a whole and it did fix the issue and here I am a year later running into the same issue thinking it could be the pedal and your comment gave me the extra boost I needed to go okay ya I think that’s more then likely the issue if not then I have a warranty on the throttle and I can replace both throttle comes with the sensors and all the good bits and if this doesn’t resolve it then I’m thinking imma have to get at the brain and check fuses
Thank you so much for this video! It just solved my problem and saved me from getting a new throttle body!
Glad it helped!
I just wanted to say thanks for posting this video. I did the exact same thing you did with the polish and was about to drop some serious cash into a problem that was so easily fixed. Thumbs UP!
Glad it worked out. Been quite some time now, and it has never returned.
Good vide I have a problem car starts and after minute or 2 stalled I got 5 codes about the throtter body related on and going to replace the hole throtter body I hope that take care the problem
All is good. It is possible you had a spot of Ware in your Petrol..Combine that with a mi-nute bit of sludge. Then you have a vehicle pregnant with a common Belly discomfort. Remember a solid High Speed run for five minutes,also helps discard carbon.Depends on the pace you drive in your area of space. Constant slow is not good..But I enjoyed the video.I save the good ones on "watch later." (like yours) Has been a life saver for me.
When I first got my 2005 mustang gt the dealer put in a new battery. After that once the car got hot. The car ran rough at idle and would stall. Read around and found out cleaning it would help. I did that and haven’t had any problems with the car since 8 years later. I carbon clean it every few years now. So if your idle is rough especially after disconnecting the battery. Clean the throttle body.
Thank you so much man I thought my transmission was done for🙏
Glad I could help
thank you so much for this video
Oh and honestly in order for it to work right you need to have the battery cables off everytime you add a part or change a part so that the computer starts fresh
My car doing that right now. I just put a airraid cool intake air system on it and ABBK 62mm throttle body and I'm having the same situation.
Hopping it's just need a tune. Waiting on the tune file now
Am I supposed to run the car w the ac on?
Oh bro I replace my throttle body n now that pops up n my over drive dose tooo
When I got it back I rev it when I first start it n pop up
Think my throttle body still messed up n maybe my trans
Nice well at least I know which wire to test now lol sum is up with my sensor or connector idk or unlikely could be the pedal sensor switch .... but I find it odd if it’s the sensor because I was getting the same sensor code with my old throttle body an sensor an I brought it used off line crazy of both of the sensors are bad lol idk ima test it ... but I had this new throttle body for months finally decided to put it on an it deff likes that cleared my throttle stuck open an throttle stuck closed codes an I think the other code it cleared so now all I need to do is figure out the sensor problem which idk like lil small simple stuff like that is fun to me cuz u kinda get to jus take it easy no crazy physical effort needed not getting super greasy an shit but anyways of u see this and make it this far did u have ur ignition on when u did the meter test on the sensor?
I’ve been having this issue every since I put my bigger throttle body on puts my car into a idle only mode showing those same codes any luck figuring it out? If so it would be helpful thank you
@@HydraHiii it could be that you might need to clear the computer which I remember is sum process where u take off the battery wire an use a jumper wire to discharge the energy or sum so that computer can relearn how to run with a different air flow an u know I act know i replaces the sensors on the throttle bottle but I think it might have ended up being plug that goes into the sensor i did re wire one of the plug an I’m try to remember in pretty sure it might have been that
Im having a similar issue with a VMP 163R monoblade on my Shelby its throwing 2 codes P2104 and P2112 im going to replace the electronics on it from my stock Throttle Body and see what happens if it doesn't fix it ima check voltage
Good luck with it. I would think the voltage range would be the same.
Did you ever fix it?
What if mine doesn’t change ?
I just wanted to know if you know anything about the 07 mustang 4.6 l my throttle didn't work at all since I changed all the I have not changed that one yet I bet that's probably the one my throttle does not respond at all now like pushed to the floor don't do
The throttle is connected by wires to the throttle body, through the computer. Not sure I understand your exact situation, but the stepper motor is on the right side of the throttle body (looking at it from the front of the car). That is either broken or the connector isn’t connected. Otherwise, it could be the connector on the gas pedal, or a defective pedal. If you take the intake tube off you can see the butterflies on the throttle body. Have someone turn the key on while watching the butterflies. It should make a noise and cycle open and closed.
What would be a good tps voltage on the throttle body?
1.19-1.31
For the love of God, Thank you! I was about to do the same.....
It did not polish up very well. Looks better, but it’s a cast part, not machined. So even after polishing, the metal is pitted. Having said that, I would still do it again.
What if the voltage doesn’t change when you move the butterflys
If you have a good connection and good voltage, but it doesn’t change when you open the butterflies, the sensor is bad.
I have a wrench light on my 2010 mustang gt...had diagnosed and the mechanic said it was a sensor triggering the torque converter clutches.....I replaced the throttle body, wrench light is still on....
Did u find the fix
Did the problem return?
My 05 GT has a idle problem sending it into limp mode with similar codes..I cant figure out what it is
Did you measure the TPS voltage? Is your throttle body clean? Were you messing with it (like I was)?
@@Just_Mark the voltage is within spec..new TPS..new MAF..BBK throttle body (been cleaned countless times). If I flash between tunes, its fine for few hundred km then comes back. Seems to happen most often after been driving for 30 minsor so.
Been trying to fix this for a long time and Ive just about had enough.
Last week I tried replacing the actuator motor like you did...Made it worst. Its just rediculous.
I never thought about checking the butterflies..It seems very unlikely though
I would definitely try adjusting the butterflies. Just crack all 4 torx bolts loose, press them back into the bore, and snug them back up.
Tried all of this and no fix, do you think a whole new throttle body world work?!?
Zach Antonacci : I can’t really answer your question. What do you mean by “all of this”? Did you replace parts? Adjustments? Clear codes/memory? It’s just too difficult to tell you what your problem is without troubleshooting it myself. I’m not an expert. I did this video to show what a I did to fix my issue, and tried my best to explain why I was doing each step.
My mustang 2010 dies at idle if I unpress the gas pedal . Has new air filter new spark plugs cables battery egr valve maf sensor . Idk what else could it be .
That’s a little different than I was having. But it wouldn’t hurt to make sure your throttle body is working
What happens if I try to move the black little circle on the throttle body I need to adjust my voltage, it’s taking me to limp mode
You will likely break that adjustment because it’s just plastic and lock-tited in place.
Just livin’ with Mark thank you, Lito tunes said the same but another tuner said to move it (Ortiz performance( my wrench light was taken off via tune by Lito something Ortiz performance couldn’t do
@@cheko4440 yea I broke mine like it was meant to lol
@@cheko4440 that’s because Lito knows how these cars operate.
@@KapcomRacing yeah he got it running first base tune! That’s crazy i couldn’t enjoy my car for years but thanks to Lito I can 🙏🏻
So what exactly did you do? Lol..basically you're saying that lil retightening of the butterflies is what fixed it,no?
Did the car die when you pushed in the clutch?
Mine’s an automatic,
I have a 2006 v6 mustang and I was driving a little fast and the (engine failsafe mode) came on how do I fix it?
My car is weird I replaced the whole throttle with sensors and and still won't start, been parked for two months already, and still does the same today
Check your crank position sensor and wires going to it mines sat for 6 months because of the two wires was touching
@@FbERicoEsco Thanks, actually found out engine has bad compression.
Good video new subscriber here
My 06 mustang gt keeps stalling it runs on just fine then it dies put it starts back up idk wtf is wrong with it and we ran the computer only reads the throttle body is open by 25% idk wtf to do at this point
Check the TPS voltage, like I did later in the video. As you open the butterflies by hand, the voltage should go up smoothly.
Map or Maf....but you know the 2 into 1 knock sensor under the plume...that may be your real problem
Mine
