Clean out your IAC (idle air control)/ air bypass valve and also the throttlebody around the butterfly...

Should clear up atleast 2 of those codes.

A friend of mines had the same problem with his 91LX. Turns out the Mass Air Meter was going bad.When he replaced it the engine stopped shaking

mine shakes like crazy too. when i hit the throttle it smooths out..... New motor and tranny mounts too.... Ive just learned to live with it. Its kinda cool at stop lights i think cause with my e cam and the car shakin a little it'll scare all the little ricers lol!!!!!

One other thing to think about....you may have a vacuum leak causing your idle drop and your engine to try stalling
