If a 93 Tracker tach jumps around at 20 to 30 RPMS is the engine missing?

it sounds like you maybe having a ECM problem, if it seems to work better cold and then when it warms up it starts to miss you maybe losing your injector pulse from the ECM. They are having problems with the ecm's from 1989 to 1994 on the Trackers. I repair them for $125.00 with a 5 year warranty.

A cars tach jumps and runs with engine rpm.Sometimes if it jumps and changes engine sound,the throttle position sensor needs changing.If it jumps with no engine speed or sound change it means your alternator is going bad.

You will definitely know if your truck jumps out of time. The engine will run very rough. The engine might not run at all.

Yes, there is a distinct possibility. This is an interference engine, and severe engine damage will occur if the belt breaks or jumps teeth.

If your engine jumps when accelerating, or when certain noises are made when engine torques.
