    2005 LS V6 missfire.

    Could be, but it was doing the same thing before I replaced the coils, and it runs good below 3500 RPM, so I'm thinking it's something else, just rather not take the shotgun approach and start replacing things that won't fix the issue, more than I already have.

    Cheap off brand coils, didn't replace o rings on intake, just put Indian head on them. Not sure where the pvc is? Does it have a Schrade value for the fuel pressure?

    2005 LS V6 missfire.

    I have an 05 LS V6 that is missfiring over 3500 RPM. Under 3500 the car runs fine and throws no codes, over 3500 I get P0300, P0301, P0302, and P0303. I replaced the Plugs, coils, and wire harness to coil connectors. I'm a a loss for what maybe causing this, but I remember reading somewhere...
