When first starting up the engine idles really funny the needle moves up and down alot around 1500 +/- 400. Though a quick small stab to the gas fixes the idle. Once the car is warm idles fine to.



The engine runs really strong. Any ideas of what's up? also when I free rev the engine I noticed that if the revs climb slowly when I use the gas, the rpm's get knocked back down a bit around 1500 rpm.



Bad vacuum line? Bad ground? Other wise like I said she runs great! Thanks for anyones input.

 

classic TPS problem...



adjust the throttle position sensor first, if it doesnt adjust it needs to be replaced

 

Cool Thanks I'll research the TPS a bit.
