I have a 92 LX with the 5.0L and a vortech blower. It has 48,000 miles. The problem is on cold start, it starts up but then the rpm drops right off and stalls. The only way to keep running is to give it some gas and even then the rpms bounce from about 1200 - 500 if I can keep it at a constant above 1500 for a few minutes then it smooths out. Engine is not throwing any codes. I have put in a new EGR valve, checked for vaccuum leaks and did a good cleaning on the IAC. I have also ruled out o2 sensors. Does anyone have any other suggestions.
have the same problem?
