That looks exactly like the code that came up on mine about a week ago...i'm running the 87 perf too. i returned to stock and then checked for codes again, and none came up...i then reloaded the 87 perf tune and no codes again...still running it with no probs.

hmmm..That gives me hope of a computer glitch? simple fix... Did you run for any length of time on the stock program before going back to the 87 performance or just load them back to back?

no run time at all...i got to work and shut off the truck and installed stock tune right away..checked for codes and then left it for the day...next morning installed 87 perf again. my codes came up as yours but bank 2 also. went really gutless...thought the fuel filter was gumming up kinda feeling. and would not rev over 3000 rpm.

OK, BOTH of you have pretty new trucks, still under warranty. And, you are having similar problems. Caforddude, I doubt NS ran it at stock for long, probably just long enough to "reboot", so to speak. I'd try that and see what happens.

Regardless, though, I don't like what you're both describing, and I don't have a fix. I doubt it's really a problem with the trucks, or the tunes, but some sort of unforeseen interaction/side effect of mixing the two. It happens in computer programming all the time and CAN be fixed, once the cause is found. It's usually something so simple it's hard to see.

I think Bill needs the exact code number to make sense of this. Can you provide it?

(One more thing for everyone: In engineering, if you don't have failures, you're not advancing and pushing the envelope. No one wants engineering to operate that way).

Well I reprogramed it with the stock tune, ran it around the block and then programed my 87 performance back in.

Same issue, same code. Is it possible this is a tune related issue meaning a coding issue not that the tune ruined my truck or more then likely a component issue.

I think for the time being the best course of action for me is to program it back to stock and run it a bit and see if the same problem happenes. From there my logic would be: no problem, tune related..Problem mechanical related....

Agree? disagree?

At 32xxx miles I don't want to wait around to long to see if I need to get it to the dealership before the warranty expires

What I really think is that Bill needs about five alter egos so he can jump in and help you figure out the problem.

I can't believe you'd have oil pressure problems on a new truck. And, if that were the case, the problem would not go away when you returned it to stock. Are you trying to adjust "Custom Options" when you set in a program?

If none of this applies, and if there are no problems running at Level 0, I have to believe the tune is causing the problem.

If you agree, I think you should call Bill ASAP.

The only "customizing" I have done with the tuner was to raise the speed limiter to 105 and adjust my tire size. I am going to program to stock in the morning and go from there. I'll keep ya posted.

What is curious is that we've been doing minor camshaft timing adjustments since 2004 and we've never run into this problem before. Even more curious is that on trucks with CAIs, we don't do any camshaft timing adjustments because it seems to induce a little bit of droning.

I'll get a look back in the files and make sure we have no camshaft modifications. This should at least eliminate the possibility of that being the problem.

Question: Is there any specific point it sets the codes? During startup... Driving 40 MPH... Under hard acceleration? Anything you can provide will be helpful.

Take care.

I had a simialar problem last night - very rough idle almost to the point of stalling while waiting at a light. Everything seemed fine before on highway 1/2hour on return from work. Same truck, motor and tuning. This morning no problem to and from work. Same maintenance regarding oil changes etc. Could not see what codes as my programmer out for repair (self induced).
Trucks stock "trouble" light did not come on either.

Would trouble code(s) stay in the computers memory until I get the programmer back?
