Last Saturday night the wife and I headed over to Sonic for a late night shake. When I started the car, it died...wouldnt idle. I had to keep a little gas on as I shifted it into gear. Drove home fine, and idled fine as I parked. All week this it has been fine, until I went to pull into my parking spot. As I made the turn into the spot, it died. Started right up, but same situation, wouldnt idle, so it died. I had to keep some throttle on and brake as i parked. No idiot lights, no warnings...Any clue where to start with this?
