I have a 1998 Chevy Pickup with the 5.7. After filling with gas it runs terrible - shaking, misfiring, etc. I had a scan and it said there was a misfire, which I already knew. I have added several gas additives, gas drier, 110 octane gas, a new fuel filter, and a couple tanks of 91 octane gas. When the fuel filter was replaced, we dumped it out and it looked like mud. So now not sure what to do. Wondering if the bad gas could have fouled the plugs, if I have a plugged injector, or if I should drain the fuel tank. Truck runs OK when not under a load but runs poorly up hill and at idle.

I need help bad. My truck us a Chevy 1500 1995 and if I drive about 30 miles or so and hit a red light and go to hit the gas. I'll have the peddle to the floor and it will start off slow then out of no where kick in and speed up. And if I'm going down the high way and the cruise control is on and I'm going up a hill it will do that. Throttle slow then kick in and speed up.
