My buddies g/f's 96 V6 is misfiring but not sure why. They had it "diagnosed" and it gave them a "PO301" code. He said it was the number 6 cylinder. Any help is appreciated.
My car ('01) does the same thing. It only misfires when I'm driving at a steady 2500 RPM or so, and when I pull the code, it's always a cylinder 6 misfire. I've checked the plug, wire, and connections.
Dunno why it does that. I just try to avoid steady RPMS around 2500 and it seems to be happy.
i had the same problem with my car. it kept missing around 2500 RPM and game me P201. i replaced the plugs (they were fine), wires (they were fine), checked the resistance and replaced the coil pack (which was fine) and still couldn't figure out what it was. i sent some sea foam up the PCV valve one day, went to the back of my car to check the smog, then walked back to the front and noticed a trickle of exhaust coming out of my engine compartment. i determined there was a hole in the exhaust manifold gasket, replaced it, and the problem hasn't occured again.
