coil packs

[digglesworth]

So it didn't seem like anything at the time but now it might be the cause of a minor issue... The "need help" thread may shed a little more light on the issue I'm having. Pulling up to a stop causes my truck to "stumble" a little. Where the RPMs should drop to idle around 7-800 or whatever idle is set at, my truck dips down to around 500 or so, studder just for a sec, then steady itself around normal idle. It's almost like one fluid motion when it does it. When I changed the plugs and swapped the TB and the spring deletes I noticed what looked like a little corrosion on the pack all the way in the front. I used some steel wool to clean it up a bit and reinstalled it. My truck was subject to the recall issue with the hood trim causing leaks to drip on that pack. I'm thinking a little water got in there causing the corrosion... I've just started digging into this issue so I haven't made it a point to notice changes in weather/humidity causing more pronounced stray voltage issues. I've also heard H3s have notoriously bad battery cables... Can someone refer me to a good place to get the coil packs? They seem pricey so I'm also wondering if I can replace just one or if you gotta do the whole set... And, what's everyone been using to swap out battery cables...?

I had this problem after I had E3 spake plugs in for 2 day. They brunt out one of my coils and sounds a 110% just like what you are describing. I pick up one coil and started to pull one at a time and my #2 coil was bad and that fixed my problem.

For the batter I'm running Tsunami Battery Terminal but I would get terminals that has a digital reader on them if I didn't have my watch dog.

Thanks Chris. I see a lot of generic cheapo knock offs out there. But man, those certainly are expensive for oem...
