I'm pretty sure now that the problem with my truck is a bad coil pack. It is showing all the signs that it did a few months ago when I had one, only then it threw a code. This time it is not though, how can I find a bad coil pack, any ideas?

Thanks

 

Start uplugging one at a time, when you disconnect a good one the truck will run obviously worse, if you find the bad one the performance will not change. Good luck and hope this helps.

 

bingo!


start with the back ones first so there not as hot though when your trying to squeeze your fingers back there

 

jesus christ ... thanks ... that was almost too obvious I dont know why didn't think of that

 

Joe,
Did you ever figure out what was wrong with your truck?

 

I think they read 5.5k when they are good. Check them w/ a multimeter.

 

Well where thinking it may be the fuel regulator now, but I'm not sure. My laptop is screwed up so I can't autotap it yet. Eric is coming to fix the computer network so I can do it then. Either way I'm narrowing it down little by little.

 

Maybe it's that LOUD stereo blowing out the plugs
