Throwing codes

[traildog]

The only two codes I would be concerned with are the last two, I'd clear the codes and make sure that your Primary(Bank 1) O2 sensor in the upper downpipe behind the turbo is plugged in securely.
I'd clean up your coil teminals and get rid of the zzp wires also.
Does this car have an aftermarket cam installed Traildog? If so it could be responsible for the P0300 missfire code
My L67 runs and idles perfectly with the AL 103's gapped at .035, I ran AL 104's gapped at .035 before the cam and other mods previously and it ran and idled great then aswell...but hey every car is a little differnt
This car ain't halfassed, he just needs some help from folks who know about turbo setups.

Couldn't tell you about the cam. Is there a way to tell from the outside? And, you don't like the name "Halfassery?" I thought it fit well.......I'll get her fixed. Then I'll change the name......;')
