Interesting find as I keep on chasing this resilient annoying yet insignificant P0302... gold star for Neganox as I kept experimenting with the bypass of the cold start routine (aka AWS, Accelerated Warm-up System). After another month I can confirm that bypassing that routine works, all the...

Thanks, I wouldn’t have thought of that possibility. Didn’t you get a P0300 or perhaps even a code specific to the sensor though (rather than cylinder-specific misfiring code)? Very curious about it... Mine is so slight that it doesn’t seem nearly as bad as the issue you had encountered but...

Evening update: bypassing the start-up routine did not work tonight. P0302 back :-( Any other thoughts? Continuing to behave well when moving; only identifiable when stopped, especially when not in neutral/Park. I have additional sets of freeze frame data, so let me know if that’s of any help...

Thanks Neganox for brainstorming on this! Much appreciated! Totally agree on the Densos, was planning on that as soon as I’d resolve this issue (the NGK is already in for the specific cylinder that misfires). I’ve seen a number of gaps recommended, but came across this manual page for Gen 1...

Ooohhh this one has been a tricky one! Time to get input on this ‘07 CX-7! The situation in short: 125,000 miles, all stock, slight misfire in cylinder 2 at start-up or at idle (and very mild most of the time). Runs perfectly fine otherwise... but the longer a drive, the rougher the first...
