Misfire? Diagnosing bad CPS or Injector??
How do I know if I’m losing an injector? I don’t have any unusual colored smoke. My only symptom is an occasional “miss” although I don’t know for sure if it’s a misfire. On a gasser, I would bet the ranch that it would be either a coil, spark plug, or plug wire. Being a diesel, none of those components exists.
I bought a new CPS which arrived today. I hope that’s the culprit. Any other tips on diagnosing a misfire?
Oh, my only modifications are SuperChip programmer and aftermarket intake. Miles are 190K
