Missing on number 1? i have an 01 ss with a problem with missing on number 1. i can unplug the maf and the miss goes away. but i have tried another maf and the same problem occurs. i have also swapped the injector, coil, plug and plug wire around and have not been able to isolate the problem yet. anyone ever run into a problem like this before? thanks in advance.

NUMBER 1 CAUSE OF A MULTI MISFIRE 0300 CODE IS BROKEN VALVESPRING BEND PUSHROD OR ROCKER ARM PROBLEM or (burnt valves which is not very common).NOT SAYING THIS IS THE PROBLEM BUT IT OFTEN HAPPENS IN LS ENGINES.HOW DID YOUR PLUG LOOK WHEN IT WAS REMOVED FROM NUM.1 CYL?POSSIBLY WET?IF SO PULL YOUR VALVECOVER AND VISUALLY INSPECT IF IT CHECKS OUT TRY TWISTING YOUR VALVESPRINGS BY HAND.BE SURE TO CHECK (BOTH) SIDES NOT JUST THE SIDE THAT YOU ARE PICKING UP A MISS ON.
