If it doing this all the time you might want to have your injectors looked at,they are a pretty common failure on the lb7 engine! is there any smoke at idle? dose your oil smell like fuel? what for mods do you have on the truck?

8th digit of vin will be a 1 for lb7 or 2 for lly, mods are things like exhaust, chips, programers, intakes,

dose it idle rough all the time or just when warm?

When was your last fuel filter change?

You might want to try a fuel filter first but it sounds like it could be bad injectors, you engine has a 100,000 mile warenty on it and i beleive the injectors are covered even longer than that.

The fuel filters on these trucksare not the best in the world by far, it dose not take much to plug them up, i just changed one with about 3000 on it and when i cut it open it was totally dirty, and the only thing i think it was was i got fuel at 1 little back woods station 1 time while on a road trip and i had problems not to long after that, what i'm getting at is that it only takes one bad tank to screw them up!!!

looks like to me that maybe they bumped the oil pressure sender or maybe evenbroke a wire or something, thats the only way that makes sense to me as for the fuel filter and the oil gauge i dont think the guy has a clue he just knows that the flters are a problem on these trucks so that his answer for all the problems!!!!!!!!

Glad to see they got it taken care of!
