I drove it the other night.. scanned for twice as long as before the car worked GREAT.. nice day figured i would drive it to work.. (about 8 miles) when 1/2 way and needed to get gas.. stumble, and a backfire pop from the TB, pulled in to the station and filled up... Restarted, ran FINE until I pulled in the parkin glot at work.. Same thing TB Pop, then died.. Restart and I have a misfire. I got it parked.. I am guessing when I go to lunch in 4 hours, it will run fine.. cause it will have cooled off.. I am thinking it is definitely heat related..

Coils will be swapped next.. Tuesday night was cool and it was cool the night I drove it in November too, so maybe this issue has been there but did not show up in cool weather.. Not sure what else to check

I did not have my scan tool hook up this am.. probably should have brought it today
