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 that it maybe due to the timing chain tensioners?
I acts like the timing is not advancing, I can here the car backfiring out the intake at over 3500 RPM.
Help a fellow LS owner out, please, I bought this car for my daughter and she really needs it. Any insight yo can offer is appreciated, I'm really at a loss as to what needs fixed.
Sorry if the has already been covered, I'm new and didn't see it anywhere with a quick search.
