having difficultys

[caveman87]

i have an 88 K5 blazer with a tbi injected 350 and i cant make it go over like 20 mph or so, i read on a link that it could be a torque converter but isn't that only under load or could it be bad enough to do it when not under load? i replaced the fuel filter (actually still am, wouldn't connect enough leaked gas) any who, i get up to about 20 and the engine burbles and the truck "jumps" and shakes and i dont know what could be the problem

[bracketshark]

if it ain't the filter most likly its the pump. any black smoke or flooding happening?

Sounds to me like maybe your trans or tourque converter has packed it in .

Yeh definatly something wrong in your trans or torque converter. So unless you've worked on that type of stuff before it would be a good idea to take it to a mechanic.
