hi guys, just bought a 94 chevy truck with a 350 in it that a guy had , the truck was running great but with an exhaust leak in the factory "y" pipe and wouldnt pass inspection......he replaced everything with new headers, high flow cat and dual exhaust out the back and now the truck runs rough and wants to die and pops some...since I havent seen the truck in person, and other than the obvious like broken plugs or wires or #5 and 7 crossed, could the o2 sensor go bad or not work with the new exhaust? what else could I look for? I have to go pick up this truck and drive it home...3 hrs away...need to bring everything with me to make it a good runner to make the trip home. thanks for the help!!
No announcement yet.
