Here's the deal. When I initially start the car the idel is normal (700-850 RPM). But its after I drive anywhere they my idel jumps to and stays at 1250-1500 RPM. What is werid too is that if I run the car at really high RMPs (6G and up) the RMPs will return to normal idel (700-850). Any suggestions? The runs normal otherwise and I have lots of play in the throttle cable so I don't believe it's the cable itself. speedshift23@yahoo.com

 

Do you have a chipped ECU? That's pretty typical of a chiped ecu. If not, just clean out your IACV screen, and bleed the coolant. Adjust idle to where you want it.

BTW, this a fairly comon "problem".
