engine bucked and clatter

[kompressor]

Had a hard day of mountian pulling through Oregon and over Siskiyous. When pulling out from a stop in Redding Ca the engine bucked and there was a loud ratteling sound. The cel came on with codes 0234,0237,2146. I had the #5 injector replaced before leaving home. Any ideas what could have caused this? I guess I'll have to have a dealer check it out in Redding. I read what the codes mean, but that doesn't help me. Thanks for any ideas.

Did you ever figure out the issue from a few months back ?

The #5 injector was bad, failed the return flow test. Dealer replaced it and it was running good. Engine still is running smooth will try it again tomorrow. I still have some passes to go over so I am quite concerned.

Any ideas what could have caused this?

From those DTC's and symptoms, it almost sounds like you may have had one or more injectors malfunctioning. If it had been the P0236 and P0237 alone, I would have guessed a failing MAP sensor. But according to Dodge diagnostic procedures, that P2146 points to one of more injectors experiencing some sort of electrical fault. Could have been a problem with one or more injectors, a wiring harness problem, or the ECM.



Best of luck to you,

Problem fixed. The wiring harness going to the number 1 injector rubbed on the plate that holds my Pac Brake compressor and there was a pinhole in the insulation that allowed it to short out to the plate. Lucky to have it found. I had taken it to Crown Motors in Redding CA and they got me in right away.

Problem fixed.

Glad to hear it and thanks for letting us know the outcome.
