My car will start, but not idle. I have replaced the IAC valve, and it worked in the drive way. I didn't drive it that day. Today, 2 day s alter, after driving the car for 10 miles, the same thing has happened again.
Will start, drives, but not idle. Car dies at about 750RPM.
I wonder if my next step is to replace the mass air flow (MAF) or the throttle position sensor.
Ant ideas?

Hello, usually with an idle issue, I take the throttle-body off, give it a good cleaning, make sure the passages are clear, go from there.

Are there any codes? Some of the national brand autostores will check codes for free, if you can get down there.

Just returned from autozone, no codes. In addition, when starting car to go to autozone, the car started, idled and drove fine. At the store, a 2 mile drive, the car would not idle again.
