I honestly don't know what's going on and it's getting slightly irritating now. For the past two years since December 2017, my car likes to buck like it wants to take off by itself when sitting at a light and idling. The list of things I have done to try and fix this problem is:
Replace MAF sensor
Clean the throttle body
Replaced the throttle body with a used one
Replaced spark plugs
Replaced coil pack
Replaced Brake booster and hose
Replaced intake snorkel that attaches to throttle body to air box (4 times)
Replaced intake manifold gasket(twice)
Replaced valve cover gasket
Replaced TCM (that actually failed though lol)
Replaced PCM and ECM combo
Replaced Fuel Pump (twice, never ever buy GMB brand fuel pumps ever again. Sticking with OEM)
Replaced Fuel filter
Replaced Fuel injectors
Replaced Purge Valve solenoid
Replaced MAP sensor with a used one
Also replaced both O2 sensors and catalytic converter with ZZP downpipe and cat combo.
I'm honestly lost with what in the world is going on with my car and I refuse to give up because I love it so much. After I replaced the Fuel pump my hesitation under acceleration had stopped and I'm finally getting the correct mpg my car is supposed to have and long term fuel trim is between -3 to -12. Anything would help. Thank you for taking the time out to read my post!
