car is misfiring, need some autotap help ok, i posted a week ago that i was having problems with my car misfiring. you can see the post here:
https://ls1tech.com/threads/showflat...=7&fpart=1
basically the car just starts running like crap. the longer it runs, the worse it seems to get. i've checked all of the valve springs and they're fine. so, i bought autotap so i can see what's going on. the only problem is i just got it today and i'm not real sure what to look at. someone please help me figure out what to look at to diagnose this problem. i tried looking at current cylinder misfires but it seemed ok (every cylinder was reading 0 except #6 read 6). at first the car idled like nothing was wrong, then it started to get worse. when i would rev the car at first it reved just fine, but after a few minutes it started missing or something and it would pop as you would rev it. sorry for the long post. TIA, Kit

Re: car is misfiring, need some autotap help Look at misfire history with the car off, and pull up the dtc codes from the computer. That should lead you in the right direction.
