i have this problem when my motor is idling around 150 deg. ive replaced the IAC motor twice and i still have the same prob. and the longer i let it idle the higher the rpms go up when its trying to compensate ans the lower it goes when its dying. until it stalls out completly. any ideas?? thanks

You need a custom tune

I mean get a professional dyno tune, not your own adjustments.

I know these are completely different cars, but I had the exact same problem on my eclipse and it turned out to be an early warning of a blown headgasket. Something to think about...

Oh brother...We all know that the mixture of coolant and oil is one of the other signs...Get it checked...Better now than driving home one day and having your car overheat because of the coolant leaking.
