i have a 2005 ford mustang with hesitation on warm up. i have a code for a miss in cylinder 5. the spark plugs are less than 10,000 miles old. i switched one of the coil on plugs to see if that would help. no luck. cleaned MAF sensor and cleaned throttle body. please help this is my only vehicle.
swap the fuel injector for 5 with another and pray the miss moves showing it's a bad fuel injector. If not that, do a compression test of the engine to see if it's worn out internally on #5
