Lately, my car won't start on cold morning without pressing the gas pedal for about 3 times and keep my foot on gas till the engine warms up before I could drive to normal rpm/idling of 700. It used to start on high rpm of 1500 and gradually goes on normal of 700. What seems to be the problem. I know late model cars has automatic choke or whatever you call it. But when it gets warmed up, the idle seemed to be smooth and normal.

    Idle Air Control could be sticking or clogged. That what allows air to pass while you're idling.

    Could be a small vacuum leak at the mainifold gasket that seals up as the engine heats up and expands. Because of the age of your vehicle it may not throw a check engine light if it's really small.

    Check it out but also look at your tune up items like filters and plugs...
