runs rough

Have 92 chevrolet pickup 350 engine truck misses when you are not giving it alot of gas check engine light is not on runs fine as long as you are giving it gas idles a little rough but hardly noticable i have replaced plugs plug wires dist. cap rotor button map sensor has not been that long since fuel filter and fuel pump was replaced

I would check the egr valve.

I will try that.Thanks

I know this you may think I'm bein a smart a**, but have you ran any fuel injector cleaner through the thing? Also, I'd have it timed. Mine was runnin kinda rough too, and I think it may be a fraction of my problem.

Tried the fuel injector cleaner and replaced the egr. valve i will check the timing. Thanks
