My car sometimes hesitates/stutters when I'm driving. Also when the car is stopped and I try to take off, it may have a very slow reaction time/loss of horse power and then it will all of a sudden pick up speed. THe check engine light will blink several times then go off.

Ive seen this on a few of these. 1st thing is 1st. Replace the fuel filter. Also check the coolant. For some reason, low coolant will cause these to act up. If you still have problems, get a new ecm, and have it flashed to your vehicle.
