Poor Acceleration Stalls at idle

I have a 1994 Chevy blazer 5.7 4x4 a few days ago I had the fuel filter changed because the engine was starved fuel. It has been running fine until today the acceleration is almost nothing and it stalls at idle.

    Ok I'll try it let you know tomorrow

    As soon as I go to the shop the Blazer would'nt start unless we poured gas straight into the TBI. So we ended up droping the gas tank and changing the fuel pump. This fixed the problem. Thank you on leading me in the right direction.

Check the gas cap too. If the vent is failing, you will be getting a vacuum effect in the gaas tank. For every pound of vacuum, you will lose a pound of fuel pump pressure.

It likely needs a fuel pump, hook up a fuel pressure gauge, it needs to be 11-13 psi

What needs to be checked when my truck has poor acceleration going up a hill? Why does it have no power and then have surges of power


depending on the model of truck , it could be the throttle body that causes poor acceleration ,could be the fuel filter if the engine starves for fuel it will affect the performance , yo should check fuel pressure and volume on the fuel system ,it could also be the eger vavle most newer trucks and cars have linear eager vavles and if the stick a little open on idle they can cause surging ,poor acceleration even missing . if the check engine light is on find out the codes and go from there . on older models it could be the TPS or the IAC v, but i would need to know what codes are in it first . It could be as simple as bad fuel .or a vacuum leak

Intermittent miss


is this a 4.3 engine, if so A common complaint with the Chevy 4.3 engine is that it doesn't idle well, it's loud and makes awkward noises. Examples of this are staling, lurching and poor acceleration. being you checked the plugs and wires. Look for corrosion, breaks, exposed wires and loose connections.Lack of oil will cause a knocking sound in the engine, stalling, poor acceleration and eventually engine break down. check all vacuum lines closely. good-day!

Just some quick checks: I'll assume you haven't received any error codes.
fuel filter,bad gas(water in the gas), indication of failing fuel pump(the 4.3 is notorious for its pump problems),dirty spark plugs, clogged fuel injectors, failed fuel injectors, MAF malfuntion(mass airflow sensor), I could go on...
