I have a misfire code consistantly on one cylinder. I have put in new plugs and wires, cleaned the coil pack (for tracking), checked the ohmeter rating for each bank on the coil (all 13.75), swapped plugs to check for a faulty plug. On cold start (heated parkade so not really cold) it starts with no problem but when put into gear I can feel the hesitation or miss. This is not enough to trigger the check engine light. On load such as going up a hill the light starts to flash and then stays on steady when under low load. The light either flashes or stays steady depending whether under load or under no load. When warmed up and under hard accelleration it may stumble a bit - or not. Very frustrating. Any suggestions out there?
