Re: help me please!!!! tuned port injection
Sounds like your fuel pressure is too low. Should be around 45 PSI at the rail.

true. also, there is no "e" in Camaro. sorry. just sayin.'
I am having a similar issue with my Formula 350, but the fuel pressure is good. my next two moves are to replace the ECM ($85.00 with core) then the MAF (practically new A1 Cardone unit).
