Buick Lesabre '97 is running terribly in cold weather.
I live in south central Idaho and we've had incredibly mild winters this past couple years. This thanksgiving, though, the weather has turned awful and my car is running terribly and I'm not sure what needs to be done to avoid.
Today it stalled out entirely.
When starting up, the engine takes a couple seconds to turn over. When driving, the car won't accelerate beyond ten or fifteen MPH.
Yesterday, that effected only lasted for a couple blocks, but today, it was worse. First I just took it straight out, but quickly realized something was wrong, so I went back home, but after waiting for several minutes, it was still bad and the vehicle stalled out.
It started back up after a few minutes of trying and waiting. It ran pretty smoothly back to my house.
Right now it'* starting up alright, still stalled out a couple times, but I've taken it around the block a couple times and it seems fine.
I'm not sure if it was just cold and I jumped the gun trying to take it out before it was ready, or something else.
The car was a bit low on coolant when I checked it, added more pure antifreeze, oil levels looked fine. I had quite a few codes, but only one persistent one, p1675. Some of them did look relevant, like an heated O2 one.
