I have changed the spark plugs, cleaned the injectors, checked the mag timing (just installed after 500 hour inspection and new distributor block), and had a mechanic check the idle fuel pump pressure and idle mixture setting. I also did a compression check and all cylinders are above 60/80. There doesn't seem to be any difference in drop with each mag at various RPM's. I have not changed the ignition wires. Any ideas on other things to look for?
