Still runs rough

I changed the egr valve and plugs and wires . Still runs rough when at idol !! Anyone have any ideas wht

 

It's a 1989 4x4 pickup 22 r 110k

 

Did you check the air filter for blockage?
Or maybe a vacuum leak.

Is there a CEL? Need more info?
Could even be something like water in the fuel.

 

Valve adjustment maybe, but at 110k it should be okay.

That's super low mileage for a truck that's 25 years old. Might be varnish or corrosion in the fuel system. Might need a complete disassembly and cleaning of the throttle body and injectors.

 

+1 on the air leak. get a can of wd-40 and spray around the vacuum lines. If the idle rises or falls, change that line. Did you inspect the rotor and cap when you changed the wires?

 

Yes that is correct !!
