2010 jeep patriot sport AWD 2.4L. was missing bad and had p0300 code. replaced both camshaft sensors, crankshaft sensor, sparkplugs and 1 coil pack on the cylinder that was misfiring. cylinder 1 is the one misfiring. i swapped the fuel injectors of cylinders 1 and 2 to see if it was an injector and cylinder 1 still misfired. while it is running with the misfire i can remove the plug to the coil pack on cylinder 1 and the motor stays the same, any other cylinders the motor dies when plug removed. i am at my wits end please help.
