As my sig indicates, I have a heavily modified 2001 Mustang GT. After over 2 years of work on the build, I finally got the car running. Unfortunately, I am getting a ton of coil malfunction codes: p0354, p0355, p0356, p0357, and p0358. Needless to say, the car runs like crap, but I thought at first it was just the big cams, since it took a while for the codes to appear. I've ruled out bad coils as the culprit, so I'm thinking there's a wiring problem somewhere. Any ideas?
