I threw 3 codes at the same time, p0351,352 & 353. I replaced coils a, b, & c and still throws codes and runs like poop. While its running I can disconnect any of the coils or fuel injectors on passenger side and it does not effect running however if I do the same on driver's side it almost dies and definitely makes a difference. If all 4 cylinders on passenger side don't seem to be getting spark, and I have replaced coils, would that tell me I have a short somewhere? or is there some electrical component that would effect one side or the other?
