Re: misfires in rain
Put the stock coils on and sell the crappy MSD coils. Stock coils are actually better in performance than the MSD or other aftermarket coils.08' L76 6.0L 4X4 Chevy EXT.Cab LTZ Vortec MAX with Snug top cover, Dynomax exhaust,Hptuners& K&N intake

Re: misfires in rain
I have never had any problems out of MSD coils, but Accel coils seem to be difficult sometimes. Make sure that the rubber grommets between the coils and ignition control module are in place and not cracked.- Josh<br />If you have any questions or need installation pics/help, e-mail me: Viper98885@aol.com<br /><a href=\"http://Camaroz28.cardomain.com/id/viper98885\" target=\"_blank\">\'93 Camaro Hardtop</a><br /><a href=\"http://Camaroz28.cardomain.com/id/01lincolnls8\" target=\"_blank\">\'01 Lincoln LS8 Sport</a><br />\'00 Yamaha YZF-R6<br /><a href=\"http://www.ftpp.net\" target=\"_blank\">Full Throttle Performance</a>

Re: misfires in rain
Check to make sure water isn't somehow getting onto one of the coil packs. We had a good downpour one night a couple months ago that dumped about 5" of water and my car began misfiring at startup after it would rain. Turns out water was leaking from the plastic cowl and dripping right at the base of the 2/5 coil pack. Replaced the bad coil pack and sealed up the plastic cowl and it's been doing fine since.'99 Camaro

Re: misfires in rain
The placement of the coil packs on the 3.8L is not very good. I remember years ago that people were creating covers that would not allow the moisture to get to the coil packs. They were pieces of sheet aluminum that just deflected the water. Heat soak was another big issue on those coils.- Josh<br />If you have any questions or need installation pics/help, e-mail me: Viper98885@aol.com<br /><a href=\"http://Camaroz28.cardomain.com/id/viper98885\" target=\"_blank\">\'93 Camaro Hardtop</a><br /><a href=\"http://Camaroz28.cardomain.com/id/01lincolnls8\" target=\"_blank\">\'01 Lincoln LS8 Sport</a><br />\'00 Yamaha YZF-R6<br /><a href=\"http://www.ftpp.net\" target=\"_blank\">Full Throttle Performance</a>

Re: misfires in rain
I had similar problems a year or so ago in heavy rain. Since then I replaced all my coil packs with new ones from Autozone and have not had a problem since. I assumed that water was affecting my original coil packs, then again they were pretty old.
