89 dodge omni HIGH IDLE RPM Sign In

I have an 89 dodge omni (automatic) 2.2 liter straight 4, with possibly 80k+ (meter is possibly broken). when the car runs "even after letting run for a short while" the car has a high idle in park of between 1500 and 2000 rmps which go up and down (vaccum leak?). I've had this problem before with a 95 saturn sw2, and the mechanic told me "he cleaned out the manifold and the throttle body of carbon"

also when i drive the car it clunks into gear and drives much faster than normal, but ill note that the accelerator pedal might need to be replaced since it is very loose

anyone have an idea of what this could be?

first post by the way :) nice place you guys have here!

have you checked your throttle linkage adjustment?Butterfly shut at idle?Make sure that the throttle linkage or cable does not bind. Have you checked for a vacuum leak?Has your check engine light ever came on?A bad idle air control motor could cause this or computer control of.
