DOH

Petey, I call shotgun!

Had almost the same problem on my Century dang thing wouldn't start cold would just turn and turn and turn till it got hot enough from turning then bang Had it towed twice finally on the second attempt the guy poured a little hot water on the coil pack and bam started right up .

Wow, quite the road to travel and only find a bad coil. Amen it was a easy & cheap fix though. Kinda of reminds me when my cat was going I would get what felt like a miss in the upper rpms and it only got worse as time went on. I finally figured it out when I blew the seam out on my cat passing on the freeway .

Similar thing happened recently with my 93. It was running crappy intermittently for a very long time, and I could never figure it out - coils seemed fine every time I checked (good spark + resistance). It didn’t matter if engine was hot or cold. Finally found problem when one coil became consistently weak.

The coils I got from McGrath (above) ended up being more helpful than I planned for.
(I got them mainly looking for the S1 to S2 performance gain).

I am glad to hear that Big Bad is finally running right! On top of everything I learned that coils that seem good when cold may play to a different tune when hot. Yay the Buick is running well again!

Here'* the thing, it had nothing to do with the coils being hot or not. It would pull that mid-throttle stutter at start-up, hot, cold, whatever, but when AZ put a tester on it, it tested fine.

I'm out to Dad'* tomorrow to finally get the small tent laid out and cleaned. I'll drop over to your place so I can drop off your "Most Unique Member" award

I'll be home at six.

omg


that was fast.

I think we scared a few people, and made a few people say "WTF? Was that really a Buick!?!?!?!?"

The headers sound SO good, and that ride made me start to like the sound of the M90.


Wow.

Brian, I think you forgot someone.
