The car runs beautifully as long as you're on the gas.. but it shakes like a V8 that's ready to throw a rod or something while its idoling. I changed the and plugs/wires and checked for any noticable vacuum lines that may be loose, and neither of those fixed it. If anyone has come up against this before and have any ideas please lmk.

Clean out the idle air control valve and test the throttle position sensor
