I have a 2001 Bullitt. For the last couple of weeks, I have been feeling a small engine hesitation when I am in a little higher gear than I should be (for example 5th gear at 40 MPH, 2nd at 5 MPH) . . . . At high RPMs I dont feel this hestitation . . . . . . It seems to have started this hestitation, or sputter, after I had my car parked in a 45deg incline (face down) . . . .I had a little problem get the car moving from park position (stalling -> 45deg) . . .. right after that event, I had a check engine light . .. . I pulled battery to reset .. . . .light never returned, but I have the low RPM hesitation problem???? what could this be?

 

I too have a bullitt an noticed this. Mine seems to be more when I'm accelerating I can feel it hesitate

 

My gt recently started this as well. It seems like power loss until about 3000rpm and then it hits hard

 

Check all of your plugs I had the same problem with my cobra turns out the threads were gone and the plug was just bouncing around

 

Check plugs..maybe bad coil or spark plug boot. I seen same problem on my buddies 04. How many miles on new plugs also are the coils stock?
