I'm pulling my hair out and don't have a lot to spare! Been all over the s10, truck, 3rd gen sites and not getting anywhere. 1992 gmc Sonoma 2wd 4.3 Tbi z motor. Has newer plugs, wires, cap, rotor, coil , temp sensor. I've checked the egr, tested the tps, it has a new icm. It will start and idle fine, back out of driveway 50' put it in drive and it bogs down and will barely run at anything over idle. In park it will rev freely and idle smooth. After driving it 50' down the road and back it will run rough and die. Fire it back up and it will idle smooth. The fuel pump is newer, and it has a new fuel filter. Injectors give a nice smooth cone spray. There are no codes or cel showing, and if I pull something it will show a code for that sensor. I have fuel, spark and no codes. What am I missing?
