    Teabagger, Clrussell, please clarify So the truck has a Fuel Temperature sensor but no Oil Temperature Sensor?, Are you saying the Fuel temperature sensor might be bad or somehow to blame? I've seen in other treads guys talking about the oil pumps nut loosening or how you have to pull the...

    TeaBagger2006 - please explain,,,, Is there a fuel temperature sensor? You think it is bad? Does anyone here give any merit to the dealer telling me the oil pump itself is bad?

    so that was 2 weeks ago, the truck is worked hard daily and only yesterday on the way home pulling a grade and towing a mini track loader it "went into limp again" or lost power and the driver just took it easy to get home, no one has driven since but I have every expectation that if I drive it...

    2007 Chevy sorta goes into Limp

    HI guys, 2007 2500HD, work truck with various drivers, towing and climbing a hill and goes into "limp" then seems to recover without any problem. Dealer says oil pressure switch or the pump itself, so we replace the pressure switch, still did it but not often, when loaded and pulling a longer...
