If you make a left in 2nd gear and drop the hammer after the turn as soon as it hits 4800 RPMs the car starts to hesitate. It keeps pulling but stumbles every 2-300 RPM. Any ideas?? thanks 2000 Silver Contour SVT # 1739/2150 Tinted Windows KKM Intake Custom Exhaust KKM Pedals

Anyone let me know what my car is doing. 2000 Contour SVT Black 2.5L V-6 5 Speed 2000 Mustang GT Red 4.6L V-8 5 Speed

Just like your symptoms, it was above 4500 RPM and with less than 1/2 tank of fuel. Once I filled up, it seemed to act properly again. Had Ford replace it and all is good again.
