First off - I'm driving down the interstate 70mph and all of the sudden I lose tension on the pedal. I initially thought the truck had died... but when I started to slow down I realized that I could still run about 30mph. I would give it more gas and get no response. If I kept the pedal steady, I could keep it at 30mph. It sounded rough, but not jumping around.. just sounded like an old tractor. I thought it may be the fuel filter - so I changed it. This did not help. When I let the truck sit for a few minutes, It will start fine and run fine for a few seconds.. long enough to get up to speed, then fall on its face again. I just had injectors installed 2 weeks ago, since then I installed a diablosport predator on 65hp setting - and adjusted the tire size to my size. 285x75x16. No issues before this happened. No warning at all.... Please help.
thanks!
thanks!
