My ram idles at least at 1700 rpm or greater most of the time. I replaced the iac about 6 months ago when the check engine light came on for it, but no code now. I did the relearn procedure the other night which seemed to help for a day. Usually when I start the truck it idled too high. Sometimes when I rev it up, it will go down but not all the time. And no I'm not talking about cold starts. If I rev it up and it goes down, I'll drive it and when I stop again, it will go back up. It has went as high as about 2500 rpm. Any ideas?
