Hey guys 2001 GMC Jimmy 2WD here. I have a spectra aftermarket intake, and I just completed a tune up (plugs, rotor, cap, fuel filter) The truck runs great but it randomly will shut off after starts, or when i place it in drive it will shut off. The car acts like its a cold Carbureted vehicle. Most of the time (99%) when i shut it off, and start it again it will work fine. Very random. My guess is the fuel pressure regulator or something to do with fuel, or maybe something related to the aftermarket intake. I am not getting any codes. Please help
