Recent complete tune up. Taken in for engine
vibration when idle. When get up to 10 MPH,
vibration goes away, come to a stop, idle goes
down, then car starts to vibrate and is getting
worse. When at idle, and turn on or use any electrical, vibration gets worse, heater, radio,
horn, turn signals and even during using automatic windows, engine will increase the vibrating. Gas
milage is great, runs great after about 10MPH,
no hesitation on highway or passing another
auto. Dumbfounded. Gene

Check your throttle position sensor and your idle air control motor.
