How does your car idle? When I first start her up in the mornings the tech is fine. It's not jumping high to low, it's stable but the car has the shakes. Once I get her on the road and come to a light or stop sign it starts up again. It's more like a jump every 3-5 seconds. There seems to be sometype of problem in the 20-40mph range. When ever I'm acclerating (not sure about the spelling), it feels like it's missing. Like I said it's only when I'm going 20-40mph. Any ideas..
