This is an extremely old video but if anyone new is watching, same exact thing was happening to me rough idle, engine was shaking exactly how his is, it was misfiring and this was 1 day after I bought it the car had 177k miles and the spark plugs had never been changed so if this is happening to you just try changing spark plugs they are very cheap and it completely fixed everything for me
Trying to help my brother out with his mazda 2008 3, was it because you had bad plugs? When turning car on it jumps up to 2000 rpms & stays there until a couple seconds as the car cools down.
@@daniellucatero-jimenez.1440 no I have no idea what that is if it idles at 1,500 or so I would say it’s a bad idle air control valve but if it jumps to 2000 off the start that sounds like something isn’t pulling enough air into the engine right away meaning it’s delayed and that can either be a blown circuit a grounded wire or just a bad mechanical part I would try to start the engine with the hood open and listen for any areas that don’t sound normal in terms of air being pulled into the engine that would probably give you a better idea of where the problem is and then you can go off that
@@daniellucatero-jimenez.1440 jumping rpm is related to too much air actually try checking the throttle body and the idle air control valve both of those can get all kinds of grease in them and cause them not to flow properly
@@parkerlong808 you think I’d have to check a fuse for this 🤔 Id assume I have a vacuum leak going on somewhere within my car maybe it’s intake or could it be the PCV valve?

@@rayneedaebluz that resets the ECU (computer). It basically makes the computer go back to mile number one. Think of it this way: as you drive your car, the ECU learns a few things. For example, it learns driving habits- when you speed up, when you slow down, highway and surface street driving etc. it also learns when to adjust things like air/fuel ratios and timing advances and retarding. After tens of thousands of miles, the ecu adjusts for components that start to wear as well. Things such as O2 sensors, MAF sensors, etc. When you reset the ECU (BTW every car is different when resetting), you refresh the ECU back to factory settings. If your car has an issue, resetting is ONLY a temporary fix. Look up "how to reset my ECU on my (enter your make, model and year" and you'll find how to reset it specifically for your vehicle. Good Luck!
Looks to me a typical iginition coil problem, mazda is known for it. Also check your Engine and Trans mounts(PSMM, RMM and DSTM), mounts are knwon to cause the most of the vibration in these models
How can you tell if the coils are going out? Mines throwing a p0101 a month after a new MAF. did EGR a year ago. Neither fixed stalling and rough idle. Ideas? Would Love to eliminate the engine rattle too lol
@@o0kilabot0o the same goes with carburetor cleaner too it does the same as brake cleaner that's why some mechanics mentioned to remove gaskets before cleaning with them cleaners that I have found out I found that out the hard way Lol 😂
I facepalmed watching this. Been postponing cleaning my TB due to the coolant lines. (just being lazy not wanting to deal with the mess and clamping the tubes shut) Idk why it never crossed my mind to just not disconnect them! Great to see there's more than enough room to do so atleast
Do you have a video on the removal of the purge valve solenoid? That engine ran much smoother! How is the car when you add some gas, do it run now without shaking?
I suppose yea you might have a rough idle. 2.3 are pretty noisy anyways with the thinks like intake rattles. how do u know your misfiring, a misfire is a big deal, the car would lose alot of power. And pretty sure it would throw a code for sure, no doubt.
Oh ya your engine light blinks. Very serious issue . i had it on my mazda p5 and i changed spark plug wires and coil boots . its usually coils or plugs

Dose anyone know if the Accelerator pedal sensor can cause rough idle shift problems..auto transmission .. And car cutting off...2012 mazda 3 i please and thank you
Rebel Scum That rough idle can be solved by disconnecting the negative battery terminal and pressing brake pedal for 30 second! Reconnect battery and start the car and let it idle run for 30 then turn on Air conditioner then let it idle for another 10 min! Then drive it as you would normally for 20 min on highway and local street! The "shift shock" from 1st to 2nd gear still has me baffled!
Thats the first thing I always do with a suspected misfire and I inspect the wires and coils.Ive literally seen walmart destroy my aunts coil pack in her 2001 beetle by spraying cold water on a hot part! Thank god they didnt crack the block that day!
Oh yes, a great way to mess up things. Depending the make and model of your car, you always want to disconnect the battery first before working under the hood.
Stop using a k&n filter. I works like $hit and all the dust gets trapped in my throttle body of my Mazda 2. I'm cleaning up the throttle body and putting the oem paper air filter back into my car. Runs better and has a better mileage with the oem filter anyway.

Bad idea with brake cleaner !, should only use throttle body cleaner, it's designed for the job ! Neither with the maf sensor either. I would have started with new spark plugs, also to reset pcm you need to ground positive lead to get rid of any residual current,,,
Guys I need help.. I have mazda 3 2005 1.6... When ever I on ac my car accelerater go up n down automatically.. Then I turn off Ac car is normal again.... It's only happen when I on Ac... Can anyone tell me what is problem?? Please
It is normal for the engine rpm to go up when you turn on the AC. It takes HP to run the AC, because of the compressor. If you do not notice any idling or performance issues, I feel there may be no issue. I hope that helps.
I hand A/C and engine code problems although I didn’t know the A/C was involved changed lots of things that didn’t work but changed the 02 sensor and fixed it
@Benjamin's Universe misfires on specific cylinders has to do with either coil packs, fuel injectors, spark plugs, or spark wires going to the coil pack on that cylinder. Check these first. Absolute worst case scenario is loss of compression on cylinder 4, however that isn't the cause 99% of the time so don't freak out unless none of the above had fixed it previously

Dont ever use brake cleaner or even carburetor cleaner on these cars. Use contact cleaner instead. its less abrasive to sensitive components.
Do not ever clean a maf sensor with brake cleaner
Why???

theres specific maf sensor cleaning😊

Idle air control , plugs and coils
Spark plugs my friend and new spark plug cables...
Don't use brake cleaner you need to use throttlebody fluid cleaner so it doesn't leave a residue on your throttlebody
I changed the air filter and that fixed it. It hadn't been changed in a long time it looked like.
Change your fuel filter bro! In tank fuel filters are crap. Try to bypass the in tank fuel filter with an external one.
They make MAF sensor cleaner for the MAF sensor. If your reading this, DO NOT use brake cleaner on your MAF sensor!!!!!
