DMNDSTAR87 Posted June 3, 2012 Report Share Posted June 3, 2012 Sound like the same issue I had last summer-----did u just install that gmmas? When I installed mine I needed to readjust my ISC and the problem went away---gig out Link to comment Share on other sites More sharing options...

Lance_S Posted June 4, 2012 Report Share Posted June 4, 2012 Check your maft setting on the 4 small dip switches. I think the third one is the startup enrichment switch. I run mine up to help it run fat on first startup. It was lean otherwise. Worth a check. If they are all four down, then your good. Link to comment Share on other sites More sharing options...

Lance_S Posted June 8, 2012 Report Share Posted June 8, 2012 Of the 4 little dip switches, the 3rd one over (from left to right) is the start up enrichment switch. Up will make it richer at startup, down will not. Link to comment Share on other sites More sharing options...

Skippy Posted June 12, 2012 Report Share Posted June 12, 2012 I have the exact same problem and I have not made any of these changes and I am currently running the stock air/injectors and all that good stuff. An additional thing is that if I drive my car and then let it sit for about 30-60mins it has a slightly hard time starting. Also, my car has the smell of fuel which may or may not be related. However, since I have it sitting right now and I am getting ready to do a full intake/exhaust revamp from the air filter to the exhaust tip with everything in between I have not "wasted" my time looking into it.
