My 05 duramax was cruising down the highway and just went "blah!" it kept running but barely and I was able to get off the highway. I turned it off, wiggled the wires to the aftermarket chip, started it and drove it home. I took a test drive the next day and it did the same thing after leaving the driveway.
The thing that gets me is that it will usually start normal, idle fine for a minute or so and then will go "blah!" and start knocking and running really rough to the point where you cant rev the motor at all, I assume the computor is limiting that due to the knocking...
I know that this is vague, without being able to see it, but here it goes:
the injectors have been done once before and it has been fine up until sat, no indication of injector trouble
the fuel filter was just changed 300 miles ago
I disconnected the aftermarket chip and unhooked the battery for a couple of hours and after idleing for a min or two it happened again
I had a neighbor hook up his computer to it and got the following code failures:
1. P0207 inject 7 control circuit
2. P0670 glow plug control circuit
3. P2146 injector positive voltage circuit group 1
I am probably going to pull it, tow it or what ever to a garage, but I was just wondering if anyone is knowledgable in this area
Thanks ahead of time to the JD family
I know, I should have bought a ford, the funny thing is that I had a rusty, trusty ole dodge that I sold when my boss made me an offer that "I couldn't refuse" on his "old" truck, does that cover all the brand bashing?
Thanks again!
