Ect will not be your failure.

Could be dirty throttle body. Vacuum leak or bad throttle body.

I have cleaned my throttle body and looked for a vacumn leak and found none. I have replaced the egr valve and the solinoid and spark plugs and tps sensor and the iac valve and still having idle low issues to where it wants to die. But only does it when it is warmed up. I had asked this same question earlier and the guy told me to check the coolant temp sensor which I just replaced since it was only 17 dollars to replace just drove it around the block and does seem to be better but just seeing why you are saying it is not my failure, plus how could I tell if my throttle body is bad

It would have to be smoke tested to see if it is leaking from the throttle body bushings.

That is an indication of a fault with the ISC. I would have that rechecked.

I have told you what I think is the problem but if you don't want to follow, there is nothing else I can do.

Good luck.

If the quality of the IAC is suspect, the problem would come back sooner or later.

I have no comments about stuffs from eBay as I have never bought anything from them.
