okay guys I have a 1995 GMC Jimmy 4.3 V6 4 wheel drive automatic trans with a 2500-3000 rpm stumble / miss / stutter whatever you wanna call it then stall under load. I have replaced cap and rotor, wires, coil, ICM, plugs, oxygen sensors, MAP sensor, crank sensor, IAT sensor, spider injector, fuel filter, fuel pump, and it still does it. now when I changed the TPS sensor last night it went from being under load to it does it under no load now and when driving with a load on it it seems fine. the only code I'm getting from the scanner is a 1351. any help here would be awesome guys I'm starting to run out of ideas
