NEED ADVICE ASAP

Hey guys,

I recently just blew up my HPOP. The dealership repaired that along with a new IPR and IPC. When I got my truck back it would fall on its face under slight acceleration (if you put it to the floor it will pick up and go). Also under a load at constant throttle the turbo will fluctuate between 8-10psi. At idle the turbo will just randomly spool up and the motor will rev up to about 1000rpm.

My guess is injectors due to the fact that the HPOP feeds the injectors and my just went (sent metal shavings into the oil when it died). Does this sound like injectors to anyone?

Also the mechanic started to tell me my turbo spools up at idle due to some emissions program I have. Then about an hr later (after he did some stuff and I took it for a ride) he said its my VGT learning itself. So I said ok, well how do I know when its done learning? He said it will stop spooling the turbo. Then about another hr later he told me it will constantly keep learning itself.

So basically has anyone had this type of problem, and more importantly for all you techs out there, what should I tell my mechanic he needs to check? I have had it there 4 times since the HPOP went and they haven't fixed anything at all.

Is the truck missing , shaking or putting out any white smoke? If not, it's probably not an injector thing. I'm no tech on these, but those are normally symptoms of injector problems.

Again, I'm no tech on these, I work on big rigs (where you can actually put your hands on stuff!). But my opinion is there is a problem with one or more injectors. Best bet is to get ahold of somebody with the computer crap and test each injector individually to tell you which ones are bad. Another option is to take a raytek laser thermometer and shoot each port on the exhaust manifold. The cold ones are your dead holes. Not getting fuel, no combustion...no heat. I don't have the diagnostics for some of the newer Cummins in the big trucks here...that's how I find dead injectors.
Try it and see how it works. Raytek is a whole lot cheaper than a computer!

Good luck and let us know what happens.

Alright I will try that. I highly doubt they checked the FICM. I have been asking them to check the injectors for a week and they wont even check them, they keep saying thats not the problem.

The real problem is Im pretty sure its injectors and they dont want to pay for them. I just bought the truck (5 days before the HPOP went out) so Im still under their warranty and they dont want to drop $490 a piece on injectors.

Might have to fight them a little on it. Thank God you still have warranty, though! If they have not checked the FICM...have them do that first. You might start putting injectors in and when done, still have the same problem. Remember that FICM controls those injectors.
If you can't get anywhere with that particular dealership, take it to another one. It sounds as if they either don't know what they are doing or they don't wanna honor the warranty there.

Well lets put it this way... it took them 20 days to do the HPOP IPR and IPC, no loaner car either. Customer service is pathetic, they never call back and take forever to do anything.
