My car has been poping at idle for some time now and it seems to be getting worse, I changed the plugs, checked all of the coils, and even loaded a tune from Rick at Amazon (thanks again). still no success. So i have started searching for any vacuum leaks under the hood. I used a digital Ultrasonic Leak Detector That i borrowed from my office, and it says that i have a leak by my PCV valve, (very small) and another place it was leaking is My IAC. I checked out the IAC (didnt remove) and noticed that the bottom bolt head has broken off somehow :shrug: I cleaned it a few months ago and re-installed with no problems and i didnt break anything. Does anybody have a suggestion as to how to get that bolt out of there? Its in a pretty tight spot so if i have to drill it out im sure i will be removing the upper intake If anybody has a suggestion or advice, let me have it :beer:
