I got in my car tonight and headed home, 1st and 2nd gear were fine but when I hit 3rd it felt like the car was stalling. It would not go at all, when I hit the gas it felt like it was going to die. I slowed back down and dropped it into 2nd and it was fine, but when I went back into 3rd, the same thing happened. I pulled over and looked under the hood but I couldn't see anything. When I got back on the road it was fine. I was low on gas, but not on E. Could it have just been stalling because it was cold? Or do I need to get it checked out? Thanks
