High idle

Have you checked for vacuum leaks ?

Yes I Have can't find any

How did you check for them?Also have you checked the coolant temp sensor?

I checked them visually and with starting fluid sprayed all around with engine running no change

The best way to check for vacuum leaks is by injecting smoke and watching for escaping smoke.Also the best way to spray around with carb spray method is to watch short term fuel trim and watching to spike while spraying around.also did you check the coolant temp sensor ?They can go bad not set a code and cause a high idle.

I did check the coolant temp sensor it's ok also injected smoke the only place it came out was the egr so I replaced that still the same?

So did you watch the coolant temp on live engine data while comparing the coolant temp to actual coolant temp?

Also what are your tps readings in volts at idle?

Ok here it is I couldn't find any problems untill I tested the coolant temp sensor and it showed low voltage so i went to the PCM it was loose and had worn 4 wires rubbed into I don't know how it still ran even with high idle anyway I fixed the wires now it runs fine who would know?

Thru years of experience with coolant temp sensor issues I have seen really strange things you wouldn't think they could cause but your proven wrong lol.Glad to hear you found the problem and got it all back to normal again.

I went all the way to the temp sensor which led me to the real problem Thanks again

Your welcome were hear to help.
