Engine Pings on Acceleration - Where do I start? 200 1990

I've been running 89 octane for a year or so, because I was getting some pinging on acceleration. It ping mostly went away on 89, but it bugged me so recently in new knock sensor. Ping was basicly gone. I just cleaned the throttle body, replaced the distributor cap and rotor, fixed the intank fuel pump, and replaced the timing belt. My gas milage went from 18 mpg to 23 (or 24) mpg. So I decided that it was running so much better that I'd try some 87 octane gas. Well the ping is back on acceleration (don't know about sustained highway yet because the muffler went bad and it was too loud.).

What must I do to get rid of this irritation? (other than running the more expensive gas.) Any suggestions are welcome.
