my son has a 1989 260E, 120km (70K). It is currently -36c I live west of Montreal. When he started his car it idled at around 2,400 rpm, we could not get it to kick off this idle speed even after 10 minutes of warm up. I looked through the threads but could not find a similar problem. No problem starting the car, I just called him on his cell as he was heading home and he pulled off the road and the car is still idling at 2,000rpm. I should mention that he had the valve stem seals changed today, oil change and antifreeze flushed and replaced. a compression check was done and all 6 cyl were even at 170. I would appreciate any assistance.
