hey
when i put my car in park and emergency brake on my car was going nuts. my car was reving from 1 to about 2rpms going back and forth until i shut the car off and restarted and did the same thing. restarted and it stopped. what can be the problem??

thanks
mike

 

sounds like the idle air control valve (iacv). it is located under the throttle body. sometimes cleaning it helps but if after cleaning it you still have the same problem the valve needs to be replaced. Very easy to replace. I have a new one I purchased but never installed. if you need it let me know, good luck.

 

why did you set the parking brake?

A idle like that sounds like a IAC

 

my driveway is a little steep. so i put the e-brake on. im bringing in my car to get my rear brakes replaced so ill have them check it. i just restarted my car and no rpm jumps. ill let u know jleon thanks

thanks guys.

check your throttle cable..mine did it when i adjusted the cable too tight..it also might be getting hung up
