In my 2003 Chevy Tahoe Z71, about 60% of the time when I first start it up or after driving it a very short distance, the engine will have a VERY rough idle. It will, during said odd idle, dip extremely in RPM, from the normal 700 to 200-300 and sometimes, if I do not drive continuously and immediately upon the RPM dropping repeatedly, the engine will just quit. It should be noted that I recently replaced the spark plugs with OEM ACDelco plugs and spark plug wires. What is going wrong with the beast and what can I do to correct it?
have the same problem?
