I'm stumped and looking to see if anyone has a possible solution to this!
2001 Bullitt with 77k miles. Car idles and runs great except when accelerating over 4000 rpm.
Right around 4000 rpm, in every gear, the car hesitates dramatically and occasionally shuts itself off. I've noticed that it also does the same hesitation when I am accelerating and hit a large bump.
I've just replaced the fuel filter and that didn't seem to have any effect on the problem. The fuel pump was replaced about 20k miles ago. Car isn't throwing any codes.
Anyone know what might be causing this?
MAF? COP? ECU? Alternator?
