I still am puzzled by this, when I start my car up after its been sitting for about 6+ hours it fires up. If i start it after I have already started it within the 6+ hour time period the car will not start on its own. It seems to misfire and will not run without giving it some gas for a minute then it will idle by its self. I have been trying to figure out the problem for a while now and can't seem to find it. any help?
