    Idle increases from cold start @750 rpm to 1750 rpm at operating temp. So far no codes being read, had code early on indicating MAF faulty so replaced with an after market MAF that failed within a week. Ended up replacing that with a Toyota OEM MAF and a new air cleaner. Worked normal for a couple weeks then same problem. Haven't pulled IAC valve to clean it but that is next. I looked for vacuum leaks but haven't found any, doesn't mean their aren't any though. Have had my thoughts on the ECT also, will get to that also if nothing else works. After that I will be stumped, I guess. Thanks for any input, I will let all know if something is successful, Thanks .......
