I bought a 96í z71(5.7L) a month ago and it has a steady misfire in
cylinder 2. Iíve scanned it and came up with a P302 code. It "chugs"
at idle in gear and shakes a little at idle in park. Iíve replaced the
plugs, wires, cap and rotor, fuel filter, put a k&n filter in it, had
a new injector system put in it, not to mention having a stock exhaust
put back on it. I am tired of paying for stuff that doesnít fix the
problem. The truck runs fine after acceleration, but a very pronounced
shutter is heard in the exhaust. EGR valve, Compression problem, O2
valve? Iíve been told a million things and just want to get to the
bottom of it!
