My car has been battling a slight missfire over 6k for awhile now. Yesterday driving home my car craps out! missfiring stumbling backfiring. You name it. After hitting up shbox.com and finding every which way to diagnose the problem. I came up with the coil being bad. Instead of reading ~8k ohms, mine was reading around 4k ohms. Luckily my dads lt1 equipped caprice was right next to it and i was able to just swap the coils. The car Hasnt run this good in Months! If anyones got a miss like that double check your coil! Just wanted to let yall know

If you figured out your Miss. Your a better man than 99.9% of the men on here. I have been trying to figure out my girl for 20 years.

Was that the resistance reading? I've been wondering how to read my coil, my car runs sorta crappy down low but is fine up top. I don't know if its a slight miss or not.

Edit: only a hotcam here, so I'm shifting around 5800.

Opps, I'm embarrassed. What's really bad is I used to be an aviation electrician.

Yeah, some coils aren't built for operation over 6K, like a AutoZone coil I had. I swapped over to a MSD and the problem went away.

Now that's a good one! Even better than "hows your dads car now?"

^Fear not, unless you ride in F/A-18s. On a serious note though I was good at my job, I just wasn't paying attention.

I chased a low RPM stumble and rough idle for the longest time, I just kind of gave up and drove the car as it ran well at WOT. One day while digging through my toolbox I found my stock coil lying in the bottom of a drawer. I thought it was worth the 2 minutes it takes to swap the coils to see if it made a difference. So I swapped out my MSD Blaster coil with the stocker and the car ran great. Been running the stock coil ever since.

That's funny, I ran an MSD coil and it burned up the connector, it was brand new out of the box. Plugged it in and car almost caught on fire, new AC Delco plug $50! Went back to the stock coil and haven't changed it since....

id put my vote towards the ac delco coil..had a msd one and the connector became loose and wasent holding how it was suppose to makeing it misfire and randomly die..ac delco works perfect =]
