My truck will start and idle fine when in park you can even reav it and it will run fine but as soon as you put the truck in gear the truck will stumble and stall
iv replaced the o2 sensor the fuel filter and I just resentle put new headers on it why does the truck stumble and stall when in gear

Check the TPS, MAF, and MAP sensor to include the EGR valve

Same issue here what did your problem end up being? I have changed the TPS sensor, injectors, fuel regulator, plugs, wires, cap, rotor, coil, runs/idles strong but then put into gear and it stalls out. Any ideas would be great thanks. 1990 Chevy Silverado 350 V8 5.0L
