So I picked this car up last November as my winter/crappy weather car with 161k on her. Car runs great and hasn't really given me many problems (granted I've only driven it 2000 miles this year) but I've noticed a strange problem the last month or so that occurs every so often. The car has always started up first time every time but I noticed a couple occasions where I would stall the car (it's almost as if the clutch wants to stick sometimes, mostly notice this on the more humid days) and when it does stall it doesn't want to start right back up again, I usually have to crank it 4 or 5 times to get it going. Does anyone have any idea what might be causing that?

 

To save yourself time, you should always hit the stickies. The #1 go to sticky is the Hot Topics - DIY sticky.

The top links there, #3 is the random stalling issue.
