I had one of these , same year & same problem, there is a fuel filter on the inside driver side frame rail replace it & take the truck in to get the fuel injecters cleaned for fun, worked for me, the cleaning of the injectors should be done due to all the crap that has been sent down the line since the filter is clogged, this will take care of the problem.

when was the last time you had the oil and filter changed in your transmission? Had mine serviced and got power back and got rid of the bucking and hesitation.

you have water in the gas tank, ya see over time, the in side of your tank sweats beleave it or not the water goes through your system an as we know water does not spark and as your driveing the gas and water mix and at high speed that's when it gos through makeing it act simple, well you got a quick fix my friend ,what you need to do is go to your parts store and tell them you need something to take the water out of your gas tank, no I'm not jokeing, thay will know what your talking about, now it mite take two treatments to get it out but it work beleave been there done that . good luck your pal al.

i dont know what is wrong with it . it gets fuel to the tbi but it wont spray through the injectors at all I had an 88' Silverado that did it too. I replaced both injectors on the TBI and it worked fine. The injectors cost me about 50 bucks each.

A couple hundred bucks but the insurance rates will be outrageous. Basically...enough that you won't drive 85 again anytime soon
