manually closed the egr vale on an old 351 cleveland. that helped some. Now we pull plug wires off and there is no effect on idle or roughness. I'd think at least something would change, but nadda. college kid and I had it running great--I rebuilt the carb for him, he put in new plugs wires and dist cap and rotor. It was smooth. he left it with his uncle while he visited his mother out of state. came back to (another) new cap and rotor, wires and pugs. chrome valve covers and a chrome racing type air filter. But it barely started (the egr) and still has this rough idle and black exhaust. choke is open. I'm lost on it now. just plain out of ideas. Any help?
