installed new motor, intercooler and rteck chiped pcm now i cant keep the car running. starts ok but have to give it a little gas to start once it starts it runs fine for about a minute or a little less then it wants to die and slowly looses rpm even when im on the gas. looked over everything and it all looks good even removed the rats nest and replaced all vac lines and it still the same. have the bac, abs, acv disconected and blosked off at the moment untill i get intercooler pipes welded with nipples but dont think that has anything to do with it.

 

Did you do your initial idle settings? IE adjusting the variable resistor, air mix screw, throttle stops, and timing?

 

yes
