just as topic says! im throwing code 23 knock sensor and code 41 O2 sensor, also throttle angle code#?? and electronic air controll#?? well after the car warms up it goes to about 1800 if run hard it falls to 1500! what could cause this??? no vacuum leaks! and im not sure how to check iacv? any help is appreciated!

 

check what you have your throttle cable set to. As for all the codes...im guessing something has fouled all the sensore. Try adjusting that trottle cable, disconnect the negative battery cable to clear the ecu, then see if anything changes.

 

ive disconnected neg cable many times! but the trotlle cable is good throttle plate is shut all the way!

 

bump!

 

someone!

 

Is your car only revving up to 3Krpms or what?

 

read title 3000rpm idle!! when i start it up it goes up to 3000 at idle, then after driving it it goes down to 1500, but actully today it went to 1000 after a 2 hour drive! throttle cable is good, and no vacum leaks! what else could it be??

 

umm did you over rev it by any chance, or like miss-shifted?

Once I miss shifted it was kinda bad and the car was idling higher then normal but I'll say that after a week it went down to normal....

Just my 2 centavos on this...

 

no over revs!

 

bump!!!!!!
