Revving idle (bouncing from normal idle to higher RPM) is usually a vacuum leak/ idle set incorrectly. Dying idle (bouncing from at or close to normal idle downward to almost stalling) can come from almost anything else. Bogging when you floor it from a stop is usually weak ignition. Hope this helps find the problem.

it goes from normal to almost stalling it doesnt bog it cuts in and out bad till 3000 doesnt matter partial throttle or full it does it some days others it dont

If it doesn't bog when you floor it from a stop then the ignition probably isn't the main problem. The most likely causes are compression & timing. Timing's easier to check but the comp sounds more likely.

Have you checked the plug wires, distributor cap, rotor, and ignition timing?

Any CEL codes?
