Hey guys
I'm getting a deal on a 99 vortec 4.3 for a new project. It has 21k miles on it. It has a misfire on the #5 cylinder. We have changed everything we can think of, 3 computers, wiring harness, all injectors, all sensors, 2 fuel pumps, wires, cap, 2 distributors, the only code that comes back is #5 misfire detected. It happens at about 2800 rpm. Would a bad valve spring make it misfire?
Any ideas would be GREAT!!!
