Your base idle may need to be adjusted. If its too low, when it heats up, the car won't have enough fuel to stay running.

You also may want to think about replacing the capacitors in your ECM if it has not been done yet as this is one of the signs of a bad ECM.

I wholly agree with jking29. After a few months (and several new parts) of trying to fix my hesitation issue, I discovered my ECU capacitors were leaking. I had it repaired and all is good. The twenty minutes it will take you to pull it is time well spent.

I have the same problem. And I don't know what to do. I can tell you a few things you should check. I already checked mine and my car is still messed up. Check your vacuum hoses make sure everything is good. Check spark plug gap and spark plug wires. Make sure your EGR valve is working right. I thought mine was broken. because when they break they stick open so once your cars warms up it should close but it doesn't and i can see how that would kill your car. You can also check your ISC motor and adjust your BISS screw. If you don't know how to do any of this stuff email me or something because i need to find someone that has had this problem and fixed it.
