my 1999 cav(2.2l) has a strange problem: It is easy to start engine when the weather is cold while hard to start when warm(long cranking time, but never failed), especially after using it 1 more hour. I repalced coolant temperature sensor/air intake temperature sensor/ spark plug/bettry, however nothing happen till now, what can i do? anyone can help me?

I would check your spark plugs after you have warmed up your engine. It is possible that oil maybe geting on the tip.
