The other day it was really cold outside over night. When I went to start my car it wouldn't start unless I gave it some gas. It ran fine after that. When I went out for lunch it wouldn't start again unless I gave it some gas, but this time if I took my foot off the gas the car died. It's ben doing that now for two days. I had to two foot it to work today. Any idea what the problem is? I know it has to do with the fuel line, I just don't know what.
