99 vortec 454. Spit and sputterin

[Bricksack]

I know yall are tired of seeing my posts ha. But I can figure this out and dont have money to replace everything.

Just replaced the distributor the cap and the rotor along with the plug wires. Runs alot better but still has a little jerk to it. Acting as if its loosing fuel pressure. Going to change the fuel filter tomorrow see if that does anything. Really only does it at acceleration. Cruise its not as munch.

Any body got any ideas im not thinking of. Injectors or what not?

Thanks in advance.

replace fuel pressure regulator and fuel injectors, the stock parts are a known problem area on these motors.
