That car is just horrible for showing misfires... I had a 97 intrepid that was also showing number 6 was misfiring but the miss was really on cylinder 1.
But just missing the cylinder altogether. At least I can confirm with a lab scope. And there is no mistaking a ignition miss. I will check if my Pegisys. Shows misfire counters on this car and if that cylinder is there.
Yes this is a known bug its been fix at the moment and will be released on the next update scheduled to be released last month but its not yet completed hopefully soon
This big chrysler update I hope it comes soon I couldn't even get codes out of 02 dodge R2500 5.9L cummins kept saying something about missing registry files or something to that affect and a exclamation mark next to pcm
