Soo any ideas would help. W210 E430...took off throttle body. Cleaned and polished. Re-installed. Now high idle. Was getting code p1580 (no more). Thing idles at like 1,000 until I touch the gas, then jumps to 2,000 and stays there when in park. Pretty normal operation when driving except “pronounced” down shifts when stopping. Can any competent Oppo help another Oppo that ruins everything that is good and decent in the world. Just fuck my life.
