So i bought a 1995 c3500 7.4 454 tbi. I have several pictures posted below but the trucks symptoms are as follows. Truck starts fine and idles but once i put it in gear and press the gas pedal it stalls or tries to stall out. I bought it with a bad transmission and installed a 4l80e from a 2000 c3500 diesel. I read on here that the converter should still work even though its not the same engine. I have also changed the plugs, cap and rotor. Another thing i read on this site was that the coolant temp sensor can make the truck idle incorrectly and stall so i changed that as well. I noticed there are many plugs with nothing to plug into on top of the engine. Alternator has extra wires hanging out of it. There is a coolant sensor on the passenger side head with a melted plug and harness. I have read that this controls the fan in front of the radiator but that fan turns on still. It might be for the gauge since my gauge is not working? I have a strange suspicion this 454 does not belong in this vehicle since i even tried to purchase and idle air control valve and every part store was giving me one with two screws to hold it down and mine screws in as u can see from the pics below. Any info will be greatly appreciated.
