I am having a problem only when I first start the car for the day. It's not really bad but I don't want it to get any worse. When I first start it up for the day it kind of acts strange it take a couple of seconds of cranking to start it up and when it does start it runs hard for a minute, but after it gets even a little warm it runs prefectly also at an idle the engine kind jumps only a little bit though you can barley tell you have to be looking for it to feel it! Has anyone had a problem like this what do you think it is??
