Seized A/C compressor and High idle
I have a 1986 190E 2.3-16 with 110,000 miles. After completing a 50 mile trip last Friday, I parked in a local store for a few minutes. When I came out and started my car, it bucked once and fired-up followed by smoke and a loud screeching noise. I immediately turned the ignition off, and popped open the hood. There was smoke coming from the A/C pulley and drive belt.
I crawled under the front of the car and unplugged the a/c compressor from the side connection, and this disengaged the a/c magnetic clutch. I re-started the engine but I noticed my idle speed to be at 1500 rpm. A friend of mine suggested that I remove the main battery connection which will re-boot the main computer. So I did just that. Idle speed dropped to 1200 rpm, which is better than 1500 rpm but still not normal. How do I drop the idle speed back to normal? Thank you in advance!
