Aye, same reasoning i'm leaning towards the injects. The truck just rolled over 50k so it's not a whole ton of miles. It could probably use a new set of wires but i really doubt they're too bad. I had the same issue with the original champions though, I changed the plugs hoping it might be related (and they were due for a change anyway).

 

Don't forget the silicone grease for the o-rings

 

Injectors fixed the problem! 2 injectors were doing some funky things, #4 was all screwed up (the one gave me a missfire 2-3 times a year). Gas mileage also seems significantly better. I was pulling 16-17 on the highway before, getting more like 19-20.5 now. Still need more time to get a better estimate but there is a significant difference. Will be getting headers on soon too which will probably help slightly (when my foots off it).

Just wanted to post the results of the install which many neglect to do and leave threads like this hanging. Hopefully you guys with the same issue scratching your head will find this thread useful and save yourself a lot of money and frustration!

I know there were at least 1 or two other threads with guys having the same issue if any of the mods remember i'm sure they'd appreciate a link to this thread!

 

good to know brutha..glad you got it figured out..

 

Cha-ching!!!!!!

 

Champions and NGK's are the best 2 plugs for a Hemi. I am thinking it could be a leaking injector causing the misfire by flooding the cylinder.

 

Just ordered my injectors from Rockauto as well. Hope this fixes mine too.

 

yeah i just used the ultrapowers, they work well.

 

Glad to hear you got it fixed.
