Hi All,
I'm a new member here. I have a 95 mustang GT auto trans. Engine is stock except for headers, CAI. I recently added a different cam, very mild specs. So as others have experienced, the idle is rough, somewhat expected, but the problems is that it dies when put into gear, and also pretty bad surging in idle and in gear. I checked thoroughly for vacuum leaks. So after searching for help by moding the IAC, I put an extra gasket in place and cut through both of them creating an open space between the 2 air holes giving it a constant by-pass. At the same time I re-set the idle using the procedure found on this site. This greatly improved the idle, and eliminated the surging, and so far it doesn't die when put into gear. So my question is how do I fine tune this modification ? Just by ear ? O2 sensor reading ? I don't have a WB O2 now, but plan to. Thanks in advance. Great site btw.
