all oxygen sensors have been replaced. changed fuel filter. have taken to two different mechanics that cant resolve problem. what the car is doing is. when it is first started. it will not stay running. you have to hit the gas pedal and hold it , pump the gas for a few minutes to get it to idol right. then when it warms up for a few minutes it runs right.

Worn cylinder rings. Check compression on each cylinder and then try all of them again with a teaspoon of engine oil and see if compression goes up. As the engine warms the ring gap will close causing the engine to run correctly.
