Svtavino - Hey again. One thing to keep in mind too is that this problem is not present when the engine is pure cold, just 15 second warmup and go. After 2 minutes or so/gets to operating temp and goes into closed loop it starts. Warmonger tried this with engine hot but tricking the PCM with a resister inline with the Coolant temp sensor - making the PCM think it was only 60 deg Far. That was done as one test. Any thoughts on that? Thanks!
