Ok, i have a '98 Contour and when the car is cold it runs pretty good, but after a few minutes when it heats up it will run like crap. Slow as hell, i cant even get it to spin the tires on a gravel road from a 25MPH punch. Weve taken the car to the shop and they have said they dont know why it does it and just send us on our way. I was hoping someone else might have had this same problem and got it fixed.
