Help me solve my misfire issue
Hey guys,
I recently relocated my coils and made longer spark plug wires to reach the new location. The wires I made worked fine and didn’t misfire. I then ordered some much nicer wires and after installing those, the car began misfiring. I tested the resistance on the new wires and they’re all about 30 ohms of resistance per foot. After this I went back to the old wires that I had made and the car is still misfiring leading me to believe the issue is not the wires. I didn’t change anything else besides the wires between the time that the car ran fine and when it began misfiring. I’ll double check that all harnesses are connected but is there anything obvious I’m missing? What else should I check for? How would you guys go about diagnosing this?
