What causes my car engine to miss at mid-range to high revs?


Asked by Jan 27, 2013 at 06:04 PM about the 2003 Ford Mustang GT Convertible

Question type: Maintenance & Repair

I have a 2003 Mustang GT Convertible. Occasionally(not always) the motor seems to miss or hestitate as I accelerate thru the gears. It happens sporadically. As an example if im getting onto the "on ramp" and accelerating 2 to 3rd...speeding up...the motor will hesitate/miss at about 3500-4000rpm's. Has anyone experienced this or have an idea. Could it be the plugs/fuel? or?... Thanks for your help.

I would suspect plugs, wires, coils, maybe the crank shaft position sensor.

Get the codes read to see if there are any pending.


what gas are you using? could be the gas or could be as mentioned, plugs, wires depending on mileage i guess. air filter possibly even.


Happened to me turned out to be mass airflow sensor.


tenspeed got it right, 1st thing is to check to see any codes, could be anything from spark plugs to o2 sensors.....
