I have a 1989 560SEC and just moved up to the Central Interior of BC, Canada, from being on the coast in Vancouver, BC. On the way up the car started choking up and becoming sluggish. I've been informed by a few people that my air/fuel rate needs to be adjusted. When in idle it sputters and then eventually shuts off. When i pull up on the choke a couple millimeters it idles smooth. I am completely new with Mercedes and I am having a hard time figuring out how to adjust the choke.
Any help will be appreciated.
