I have noticed at 55 mph it very rarely does this. Its really only once I get up to about 65 that it does it consistantly.
The mileage issue is another thing. I carpool with the wife in to work and back. She is a horticulture technician, so she drives the car around the city all day for her job. I just drive to work, she takes off, then picks me up when I'm done and I drive home. She won't P&G.
I usually average 40-45 on the way in to work and back according to the scangague which I think is a bit high (still dialing it in). That is only P&Ging halfway due to this problem.
Thanks for the input fellas.
