i replaced plenum with one of the plenum kits think hughes kit. cat is gutted and i did the sparkplug non fouler for the 02 sensors. im going to replace plugs this weekend and ill see how the wires are. wires are fairly newer.

 

Wait, which 02 sensors? If you did both, that's bad. You should have only done it with the post-cat 02, not the pre-cat.

 

You should add that info to your sig, so we know what all has been done to your truck. Anyway, check out the FAQ/DIY section. Lots of good info like this, https://dodgeforum.com/forum/2nd-gen...code-list.html

 

Did you follow the TSB regarding the proper routing of the wires? Also, are you certain the wires are connected to the appropriate plug?

 

right. i screwed pre cat in like normal and did it to the post cat

 

+1 Could have a split wire and it's crossfiring with another.
Oh, okay. That's good. lol

 

I dont know how to do add info to my sig. im on my phone and dont see anything. maybe ill try when im on a computer next time.

 

maybe ill replace plugs and wires to this weekend and go fr there.

 

whats a good brand for plug wires? theres so many hard to find a good brand.

 

Do the key trick, pull the plugs for the cylinders it says is misfiring. If it doesn't show any codes pull the plugs anyway and take a look at them before you buy a new set.

Stick to cheap copper cores.... Some like Champion some like Autolite, etc...
