PT Cruiser studdering/jerking
My Pt Cruiser had been studdering/jerking while on Reverse or Drive while my foot on the brake. I recently put Chevron Techron (fuel injector cleaner) and it doesn't jerk/studder no more. I took it to the shop and had the computer diagnostics done and told me it was because of the engine's computer, fuel throttle body, throttle switch, fuel injection, and Air/Fuel Mixture Fluid. Is there such thing as having to replace the throttle body? Thanks!

Re: PT Cruiser studdering/jerking
What diagnostics?
No, you should not have to replace throttle body - There is an Idle Air Controller (IAC).

Re: PT Cruiser studdering/jerking
So, does the AIC need to be cleaned? The jerking/stalling problem has stopped. Just that running power has gone away. The tranny takes longer to make the gear changes. Before I had the transmission fluid done, the gear change would be "rrrrrrrrrr... gear change..rrrrrrrrrrrrrr...change." After the tranny fluid was replaced, the tranny went "rrr..change...rrr..change." I could feel the car run real SMOOTH. Sorry for the lame examples but hope you understand what I'm saying.
