my car runs like a dream in the summer, however, in the cold that we've had lately my car will maybe reach the corner where the cross traffic is a kinda busy street. but when i go to pull into the intersection the car sputters and dies. The idle drops too low and it's a b***** to get her going again. i dont the ecm is functional. if i floor it, the car will continue to run but barely. i am confident in my abilities, and i'm a skilled driver, however, my car takes a lot of effort to keep her alive. i think the problem is that the choke opens too soon. anyone have any suggestions? any help will be appreciated.
