| Same problem here?
I drove about 80 miles last night as the temp dropped from 20F/-7C to 9F/-13C by the time I got home. The car then sat again til this afternoon when it was back up to about 20F/-7C and when I tried starting it, it sputtered and stalled several times as I let the clutch out (while still parked in neutral).
After that, I got it started but had to give it gas to keep it running. Got it in gear, giving more gas than usual in 1st and after a minute or so it was fine. Funny thing is, it's been 20F/-7C loads of times this winter with no stalling issues (though needing more gas when starting off). Maybe because my trip last night was longer than usual, more condensation than usual had built up?
Not sure whether this makes a difference, but like today the car's usually parked on a gentle upgrade overnight. |
