I have searched all the threads and still can't figure this out. I am having trouble with my 2005 pt cruiser touring edition. 2.4. It will start after a second or two and some prayer and when i'm driving around 40 it starts to jerk and sputter or when I give it a good amount of gas. It is throwing cam shaft and crank shaft codes some times, spark plugs sometimes, and map sensor sometimes. I have changed the fuel pump, the crank shaft sensor, the camshaft sensor, cleaned the MAP sensor, and changed the spark plugs. I am kind of at a loss and thinking it has more to do with fuel. With it having trouble starting, paired with the acceleration problems maybe someone has had this specific problem?
