I cannot stress this enough to all of you guys experiencing strange throttle responses, or backfires. Especially if you fix something that was a problem over a few months in duration. When it involves throttle, fuel, spark timing these are all monitored by the pcm, but adjusted in the keep alive memory according to changes in your vehicles engine environment. Just because you changed that malfunctioning sensor or spark plug that was screwed etc doesn't mean instant harmony it could take up to 10 drive cycles for the pcm to slowly change the tables in the KAM, that is why it is so important after anything involving fuel, throttle, air, or spark to reset your keep alive memory and go through the relearn process I have posted as replies throughout this thread. Good luck and I hope this helps most of your problems.
After any sort of work involving ignition or intake you need to reset you keep alive memory (kam), you can do this by leaving the battery unhooked for 15-30 minutes with your doors open or using an sct tuner you can reset the Kam. Then once clear make sure all electronics in the car are off, put the emergency brake on, start the car let it run until the car as at running temperature, next turn on your ac full blast for 2-3 minutes, after that take the car for an aggressive 10 mile ride. This sets the stages for long term and short term fuel trims as well as throttle response.
Okay so my 2005 mustang 3v was doing the exact same thing & I kept watching this video coming back looking at the comments & turns out I went to Summit racing & got some new spark plugs & when I was taking my spark plugs out most of the 8 were dry ash so I put the new ones in & my car drives perfectly with no hesitation , sputtering or nothing so it could be some of y’all’s spark plugs. & Also I clean my air aid air filter so I know that helped also 💯💯 I hope this comment helps someone 🎉 IT CAN BE BAD SPARK PLUGS HAVING YOUR CAR DOING THIS.
Same thing happened to me. I have a 2008 v6. Replaced my fuel pump three times last year. Bought better gas, fuel treatment, new alternator nothing fixed it. Harsh start check engine light and idling was weird. It ended up being my fuel rail injector sensor. Was like $50 on rock auto
I have about same problem. All research leads to fuel pump which is under the back seat. This didn't start until I ran to empty. That's a no no. Will update when I get the new pump in Tuesday. Changed fuel filter and gas didn't look good. Research shows residue from old gas tank when ran on empty. Just a tip for yall
Just got my 08 mustang gt fixed. It wasn't the throttle body or the pedal sensor. Turns out the throttle body harness had a bad pin connection. A tie wrap fixed it. It would lose power and wrench light would come on then engine light comes on. Sometimes you could just turn it off for a minute or so and it would drive fine for a few miles then go into limp mode again.
In the owners manual usually under the transmission section it will have instructions on how to reteach the transmission. With my 02 Ford E-350 V10 any time that the battery is disconnected from the vehicle when you reconnect you have to go through these specific steps or you will just keep having problems. Your first drive after doing any repairs should be 10+ miles so it has time I that first restart to go through all the functions and save that memory
I've had this problem myself but worse and so have others. So.... start from back to front.. 1 empty fuel. 2 change fuel filter. 3 add sea foam to clean fuel system. 4 check and or change spark plugs. This completely fixed mine. Might do a mass airflow sensor cleaning too if you want. Wouldn't hurt. Also the spark plugs on these cars have a tendency to back out over time even with factory torque specks. Check them regularly.
In my case, 2012 odyssey, I had a misfire and sudden rpm drop. I checked injectors, coil packs, plugs etc, everything and could not find the issue. On a suggestion from a friend I put a bottle of HEET, and viola issue went away. Turns out I had water in my fuel. Anyway just a suggestion to others to start simple first before troubleshooting the harder stuff.

MASS AIR FLOW SENSOR CAN ALSO CAUSE THIS ISSUE, REPLACING IT WILL HELP IN SOME CASES.

Had the same problem, in my situation I needed to replace both O2 sensors, and after I did it was running great.

This was a long, stressful video goofy

Thank you for this video I got the same problem and I changed my fuel filter and I fixed it bro thanks
So you fill the tank, but what was the final fix result of this? When you have driven the tank level lower???Did you done other fix?
My 05' mustang was sputtering and misfiring for a couple weeks.
Nice job brother👍🏼🙏🏼❤

My guess is you had a clogged injector. A code wouldn't likely come up.
I’m dealing with that problem right now and I don’t know what it is so I guess I’m gonna try these few things and see what happens
For some reason I have the same issue but I was stalling as well changed my TPS and I fixed it now 6 month later the same issue
Where did you buy your steering wheel emblem from? I have tried to look everywhere
