Help!!! CEL on and now power!!!!

[WPeschel]

Ok on my way to work this morning cruising around 75... All of a sudden major decrease in power, and cel came on... P2149, P0606, P0647. The last two codes i always get every now and again from my tst, which will be fixed when i send it in for the new updates. . I just installed around 500 miles ago the GPD fuel kit. The truck sounds like it is only running on three cylinders. . I limped it back home about 15 miles I noticed egts were around 250 degrees on the way home running 50mph. . Boost and egts were in check, and fuel pressure around 20 psi when this happened. . Did the CP3 take a dump???

P2149

WPeschel,

Just had a similar experience with my 4. 5 last week sitting at a drive thru idling. Took it straight to the dealer since it was still under warranty , told them it was throwing this code. The tech oringinally diagnosed a bad CP3 just based on what he had seen in the past, but the final outcome was a #4 injector. Cummins covered under 100K warranty. Just got the truck back this morning and all seems to be OK. I think my experience is rare based upon the posts I researched here, but thought I would pass it along for your information.

After hours of extensive searching on forums it seems that this is a code sometimes thrown by the TST... . Possibly a loose injector harness, or bad injector... . I will try to check it out more when I get home tomorrow... Thanks for the reply...

Well I pulled of the TST, Edge ez, and Bully dog downloader, and still have the terrible miss... . After driving it about 30 min it cleared up, but still has a miss and cel light still on after reseting it several times... . Is there something else I should check?? Man I could really use some help on this??
