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.

No. 1-1

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
