ENGINE IDLE SPEED

1988 Ford F-250 • 197,000 miles

Changed IAC valve from another truck and it ran fine for 10mins, then jumped up to 2200 rpms again. Can not do codes yet as today is Sunday, will do tomorrow. Other truck runs fine with old IAC valve reinstalled in it. Driving me nuts. Should I wait for codes then contact you again? Thanks alot for the help so far. Bill

Why did you replace it to begin with?

You should be replying to your previous post as the person attending to you can't be running around looking for you.
