My truck idles fast when cold , which is normal. After about a minute , the idle drops down and the engine stalls. Scan code reads p1507 idle air control underspeed error. Can anyone offer a soluton?

Welcome to this forum! I think that your IAC might need to be either cleaned out, or replaced. It is a good idea to clean your MAF, and throttle body intake while you are already doing all of this.

If you plan on cleaning these out - use Throttle Body cleaner - carb cleaner might take off a coating that's on the throttle body.

Thanks, I already cleaned the maf. Will clean the rest out this weekend.
