I have a 02 camaro with cam and heads etc. I changed coils, plugs,wires, and fuel filter. I also did a smoke test no vaccum leaks my random misfire will not go away i even reset the pcm still code comes back . The car at wot feel fine and pulls like an ape no lost of power noticed but idle and around 2000 rmp i can feel the misfire the car also have new o2 sensors which reads fine and was tune with a hp tuner. My next step is the valve springs i am just tired of spending money chasing my tail. Any ideas ? It also throws a code for high or low fuel pressure but pressure is at 60 psi which is normal for the 255 pump

i have the same code. its all from my cam swap. are you sure its not just a choppy cam? mine drives fine, just the computer doesnt realize the cam is in there and thinks its misfiring.
