Rb737 Gettin' there
Rought and low idle at stop

when i am at a stop or in park, my car idles pretty rough, and about 100rpm below normal. i have changed the plugs an wires, cleaned the IAC valce, cleaned the Throttle body, Cleaned the Throttle positioning sensor, changed most of the vaccume hoses and inspected others,ive done a torque test for the motor mounts, ive tested the fuel pressure regulator, and changed the fuel filter, brand new battery, ive done practically everything i can think of and the problem still hasnt gone away, i have 85k miles and no service lights or weird sounds...car runs smoothly when driving, smooth shifting etc.....im a little lost on how to find this problem, any help or advice is greatly appreciated, thank you.
