I'm going to try this to see if it will help. My problem isn't exaclty high idle its a surging idle. If I unplug the IAC it idles down to normal but wants to die when put in gear. I am also getting an IAC Code. I have checked the voltage in the power supply and the signal wire and all was good. Any other ideas would be much appreciated.

On one end of the IAC there is a small plug which can be removed with an allen wrench. If you are careful don't lose the very small plastic washer when you remove it. We cleaned that up, plus the spring behind it. May not be totally necessary to remove the plug, but it seemed to be the right thing to do. Got it real clean and seems to be an improvement. We will remove the intake manifold and clean all the passages and then replace when we are ready to install our refurbished injectors. Also, replaced all the ignition coils. At 373K we were not sure the old stuff was worth keeping. So far running pretty well. Cleaning the intake should be the final step if the EGR is still ok.
Ok I tried this wonderful DIY thinking it might help the problem I've been having with the car shutting off as soon as I let go of the accelerator. I think i did it correctly, but it seems like I made the problem much worse. Maybe I didn't clean it out well enough? (Best way anyone?)
but now when I start the car (have to jump it :| ) It still does the same thing, but my heat temp shot way up. I turned the car off before it past the middle heat mark and it continued all the way up to red line even after I shut it off.
I'm thinking I should stick to computers not cars, but does anyone have some advice on a remedy?
Thanks so much!
