Unfortunately due to the recent icy roads in Mass. I slide, at about 25 mph, into a 15" diameter tree. Since then my car, which was running fine, won't idle, it only stalls out, but it will run if the accelerator is applied or you are in a lower gear at a higher rpm. I can't see any obvious physical signs off damage, besides a scratch on the bumper, under the hood or outside. The tree hit almost directly (a little to the passenger side) in front of the pass. headlight. I was just wondering if anyone might have a clue as to why the car won't stay running?

Thanks in advance,
Dan
