When I am at a light, my idle goes from 1.5-2, just keeps on moving inbetween 1.5-2, just wondering how to fix this...???

 

make sure all ur senors are plugged in.
i had this problem about a weekago

 

Check you're car for a CEL (Check Engine Light).
If you have one check you're Trouble Codes.

If you are not throwing a code:
a. You're Idle Air Control Valve on the back of you're intake manifold is bad/dirty.
b. You're throttle body has a fast idle thermo valve & it needs to be overhauled.
c. You have a vacume leak somewhere.

Good Luck.

 

PCV valve, throttle position sensor, or random vacuum leak.

 

thanks
