So I'm trying to complete my h22 swap into my teg, but yesterday had a very disturbing problem. The car won't go past 1500 rpms without dieing, and getting bad vibrations from driver side, I looked at the engine and and the 4th cylinder header was completely cold wheras the other 3 were hot, and I was also getting some backfire. I'm at a total loss of what this could be because it was working perfectly the other day. It all started when I screwed around with my wiring yesterday to the ECU trying to get a few cel's to go away, what could I have screwed with to make the 4th cylinder go dead or is it just a coincidence? Also, I checked the 4 wires to the ecu for the injectors. Please somone help me. I'd really appreciate and help!
