Misfire trouble code kicks my cruise off

[mrt23]

I have an 06 supercharged 3.8. My trouble is that I will be driving along and the car kicks my cruise control off and flashes the check engine light at me. You can't ever feel a misfire, but the code it sets is for cyl 1 misfire. I have performed cyl leakage test with good results, new plugs & wires, switched coil packs ignition modules and fuel injectors with no change in my problem. Has anyone experienced this problem and solved it?

What brand of spark plugs are you running and what gap?

If you are running the factory gap, I'd lower it to .050 to .055ish to see if anything helps.

Past that I'd try looking down into the cylinder to make sure the piston isnt chipped somehow or do a compression test to make sure it's at or near spec still.

I don't remember on the plugs, but that's a good idea to knock the gap a little less, I will try that. I did a cylinder leakage test and it had very little leakage on that and all cylinders.
