Seeing how I'm new to the whole Mustang thing, I figured I would try to get a few answers for my new ride. I just purchased a 2001 GT convertible with a 5 speed and I LOVE it! This has already got to be my favorite car; it just wants to be driven. I took her out for a little trip this weekend and it did pretty well. I did notice that I seem to have a problem while out on the interstate, the car wants to "shudder" like an auto with a torque converter problem. It only seems to happen at a certain throttle position; somewhere in the middle while under a decent load. I did notice that it will do it in other gears so I don't believe it is in the transmission. If anyone has any comments I'd lobe to hear them. Thanks in advance for any input!
