I just got an 01 true blue bullitt with 73000 miles. I find that when it's warmed up, it cuts out and acts like it's hitting a rev limiter. It only happens when I get on it, and if I just wind it out slowly it's fine. I also noticed that it gets worse the longer I drive it in one shot; the other day I was taking some time to drive it around and try to figure it out, and after awhile it started acting up even before the 4000 range, and with even less throttle applied.
I checked and found no loose wires, unplugged to MAF to see if it was causing it, and checked the O2 sensors, but they didnt even throw a code. I bought a fuel filter but havent gotten around to installing it yet. I was gonna pick up injector cleaner as well. I also noticed a sticker on the radiator cover that shows it was re-tuned at one point by a Ford dealer. Could it have been mistakenly tuned with normal GT settings? I can't figure it out.
EDIT: By the way, I searched, but only seemed to find posts regarding 5.0 cars.... Sorry if this has already been covered
