Electronic or vacumn EGR valve?

Any codes?

What is engine vacumn reading at idle and at 2K rpm?

What clinders are missing?

Just one or several or a bunch of them?

Flat top or old style cap/dist?

Is dist shaft side play good?

Post back any codes or check engine lights?

Try some good fuel injector cleaner. I noticed an immediate improvement in my truck when I added injector cleaner.
