Today I was truck pulling, and threw the code P0093. Yes I did a search for this topic, and found it's an injector related problems. Everything I read about this, said that there truck was running poorly, and no power. After the pulls, about 10 miles down the road the ses light went off, and the truck is running great. There is no fuel smell in the oil, full power, good idle, everything seems normal.
Could this be some sort of freak thing, or should I have the stealership look at it?

IIRC, the 0093 on an LB7 is the same as a 1093 on a LLY, Low Rail Pressure. If so, you should be OK. Change your fuel filter, and if you are not running a lift pump, consider doing it.

yes, I do have a lift pump, a single fm100, and both fuel filters have been changed about 3000 miles ago. I have pulled twice before with my current setup, and no problems. I'll run her, and see what happens. Thanks McRat!
