First time poster need help with stuttering/jerking during decel
Hi everyone,
I will freely admit im not a great car guy and seeing how knowledgeable you guys are here, I though i might get some help.
I am having some trouble with my charger and need some help.
I already took my charger to the dealer and paid $400 and the issue is still not fixed.
Car= 2009 Charger 3.5L V6
Issue = The check engine light is in. The traction control/assist light is in.
At low speeds, the car seems ok...but when i get to higher speeds (40mph and up), a few things happen.
If I keep the throttle steady with my foot, the car drives fine. But as soon as i start to slowly let off the throttle to slow down, the car starts stuttering and jerking. If I let go of the gas completely and take my foot off..it stops the stuterring/jerking and just slows down on its own. When I try to accelerate again..sometimes its hesitant and isnt as responsive thought it doesnt seem to start stuttering/jerking until i then start letting go of the gas slowly again.
I took it to dealer. They looked at the engine code and said it can be a few things. They checked the timing and said the timing is spot on and great (so im happy that its not the timing belt...hopefully). So they replaced 2 sensors (crank shaft..and another). Still the same issue and charged me 400 for the labor.
They said, the next thing to try and what they suspect is it might be a bad PCM.
Does that sound right to you guys? I dont want to pay another 400 bucks on another guess on their part. Can a faulty PCM cause the symptoms I described?
What else can it be? Something with cruise control? TPS?
Any help would be greatly appreciated.
