1994 chevy silverado 4.3 liter?

[Lenora]

All the ignition system checks out and the EGR valve checks out, no codes in computer. Problem is I can drive it 6 or 8 miles down the road and it starts missing badley and cutting out on me. What could be wrong, Idles fine now tell me what is wrong with this truck. Thank you very much.

Check your filter is water getting to it? FTRA?SSRA will do that, are they one of your mods?
BTW, why did you get rid of the Powerdyne.??
