My 91 idle is ROUGH, gas in neutral over 2k will just about make it die, the motor shakes as well as the shifter. In addition it sounds like its misfiring, i've replaced the spark plugs/wires, new intake, cleaned the maf and throttle body. Im not sure how to pinpoint what It could be, my next guess is the IACV and TPS.

You check maf voltage?

Try unplugging the maf see how it idles
