So took my truck to a dealer to see what they could do for me and he said he didnt want to touch it.
My truck is knocking, has no power, and ive picked up 4 trouble codes, 1404, 2149, 0202, 0405. I went on PPEs website and looked up the codes, two are EGR involved and two are injector circuit low...
I was wondering if one of the wires on my EGR false code elim. came loose if that would cause this problem??? or what it would be?
I was running 65 on the highway and was playin with a HEMI, then my tranny kicked into third gear, I didnt have far to go so i just heald 3K RPMs for two miles then right b4 the off ramp the truck started knocking and slowed down instantly.
Any input would be greatly appreciated.

Dealer wouldn't touch it? WTF. Sounds like you need the "FIX" on your #2 and/or #7 injuctor plug and a new dealer.

With those codes, it sounds more like harness rub at the FICM bracket (based on the definition of the codes in the DTC lookup tool here). The #2 / #7 would give you a "Circuit open" code.

That is the kind of answer i was looking for. Thanx for the input and I will check in the morning
