Re: Engine revs up
intermittent vacuum leak?
MAF sensor?
AIC sensor?
Any codes?

Re: Engine revs up
No codes as of yet, but I am not sure that it works bc I got to rewire the car. What is an AIC sensor?

Idle Air Control.
There's probably a way you can test these sensors with a multimeter, since the ECM may or may not be helping you out. Check your haynes manual perhaps.

Re: Engine revs up
Check your EGR type...if it runs off exhaust backpressure..it could be a problem with the cat or the EGR itself.
