Im having the same "popping" issue under load at low rpms and and awful "miss shake" at cruising speed as well. I have replace my plugs and wires, but the issue still persists. I have not, however, changed out my cap and rotor......could this combo be the culprit?
I have no DTCs......I DID notice the other day that the passenger side exhaust flange at the manifold was leaking,,,,,hoping that was my problem, I tightened it , but still this DAMN POPPING!!!
