Yeah even our local mechanic was going to charge $500. He said the part is $300. All 3 of our auto parts stores carried it for $150-$200. Going to try & replace it this weekend!

Thank you!

Thanks for posting back. Great job in finding the problem and trying to save a few dollars.

Note the IAC valve is connected to the engines coolant system.

Please post back with the results.

Ok, so I will loose coolant & coolant has antifreeze right? I should hose the driveway after cuz I have dogs & it's poisonous to them. Should be doing the job today. I will know best if it worked after it's 1st cold start.

Yes, some antifreeze and hose off to keep from animals.

Post back with results.

Car fired right up this morning! A little bumpy/shaky/vibration to the start, but no hesitation what so ever! I assume this may just be how the car is.

Idling normally & much more quite. Not rough at all.

Great.

These problems could work their way out.
