    Default got it fixed

    Ok after doing some searching around found the fix. it was the throttle body being dirty. but what suprised me was that when I first removed it from the engine it did not look bad at all. ended up using an entire can of seafoam and a good old used tooth brush to get it really clean, installed it back on the truck and reconnected the battery dumped another can of seafoam in the gas tank and it has been running like a new truck

    That's good news... kind of amazing at how much the throttle body impacts the performance huh?
