Running terrible

94 Convertible stock- Yesterday drove to work 50 miles ran great - last night after work started and running really rough - drove home and feels like running on 6 cylinders - shaking itself to death - this morning checked plug wires etc - all ok - when I turned off loud sucking noise like vacuum leak. Also when run RPM's to 2500 sounds like knocking. Please help.

Take the plugs out and see what they look like.

Mine did the same thing and it was MAF sensor. Mine is an 86. Unplug the MAF and see if it runs smoother. Mine was not pulling a code either.
