95 c1500 4.3 issues running

[jdeitz1979]

Hey guys. I recently purchased a winter beater that’s a 1995 c1500 with the 4.3 6cylinder. The truck will run for a while before it starts idling rough. Thump the gas and it’s ok for a minute then back to running rough. Running down the road is a bit of a challenge. Pretty good loss of power. It didn’t throw any codes so I started chasing the problem. New fuel pump, new plugs wires cap and rotor. New temp sensor and coolant sensor. No improvements so I’m not sure where to dive next. Any ideas?

Did you also replace the fuel filter?

Is your alternator charging correctly?

The alternator is charging correctly. No loss of voltage and it’s not over charging. The fuel filter looks like it was replaced by P.O. so I didn’t change it. I can to eliminate that.
