Ok i have a ses light, pulled code and its 0307 #7 missfire..

This is what ive tried so far.

swapped coil with another cylinder.
2 new plugs
swapped plug wire with another cylinder
checked valve springs and pushrods

no help still same code everytime cyl #7
without autotap this is difficult any guesses im about to cry the car misses bad. whats weird though when i pull the plug its great on one side the other is a brownish color, this is divided exactly by the ground strap on the plug.. kinda weird.

is it possibly an injector or would that cause more than one cylinder at once?

Please help Ls1 masters i need to fix this..

Thanks,
Greg

It looks like you've covered all the spark concerns. My shot in the dark says injector. Swap it out and try again. Good luck.
