05 N/A 6spd roadster 60k miles. Every few starts the car needs to have the throttle "reset" procedure done for the throttle to react. If not, the accelerator/throttle has no response or barely wants to climb rpms. The throttle "reset" procedure is done correctly. I replaced with new, the throttle body, accelerator pedal, RCM, and double checked connections to all those including the PCM. I'm at my end trying to figure it out. The car runs excellent once the "reset" has been done but its getting annoying when almost everytime you have to "reset' it to go anywhere in the car. I'm not sure where to go with it moving forward. Im not sure if there is a memory problem within the PCM that it cannot store the calibration of the accelerator pedal or another issue all together. I've tried two new accelerator pedals as well as two used throttle bodies and the new TB one I've installed. Please help with any ideas. Thank you.

 

What all you guys think about possibility the throttle body being bad? I've got three throttle pedal assemblies... I inherited this task from my pastor as he had two other people working on it and neither one of them could get it fixed it started out he had a bad throttle pedal. That I confirmed with my scanner, it is a bad throttle pedal so he bought a new one and somebody put it in and they received the part with the pigtail plugged into the accelerator pedal and the wiring cut so they assume that that's how they had to install it. I've double checked the wiring I've replaced it with crimped and did wire and extended it cuz it's so tight up there and was able to determine that the second throttle pedal was bad to start with so the throttle pedal assembly that's in there now is is good according to the scanner but it still does not rev there's no rev to it I've done the relearn the reset the read everything with the door open the door closed every which Way nothing so I'm wondering if anybody has experience had this experience and it turned out it was the throttle body because I will order one of those and try that if that's what people have experienced please give me your two cents I would appreciate it.

 

Have you tried cleaning the MAF sensor and the throttle body?
If you do it, be careful taking the locking ring off of the MAF sensor. The plastic is brittle and I broke mine. Luckily new replacements are available.
