Hey guys,

So I cleaned my throttle body and MAF yesterday. Disconnected negative terminal. Used the correct cleaners, made sure everythinng was tight. When cleaning the throttle body I moved the butterfly a little bit but not much.

Started up fine, but I notice when I'm pushing down on the gas pedal, it hangs at 2000rpm even if I'm accelerating, and eventually it'll shoot to 3000rpm. Its a super uneven jump from 2000->3000,

Any idea of what happened, what I should do? I'm leaving the negative terminal off in hopes of just resetting the ECU again.

Any help would be appreciated.

 

you need to do an idle relearn procedure. its the 6th post down

and take a stop watch with you. the ECU is very picky about timing. if its off by too much the procedure wont work.
