If a piston was not working I doubt the engine would even run. You should get the vehicle scanned for codes, I'll just give you the information on what you are going to need to check...Possible causes - Faulty spark plug 1 - Clogged or faulty fuel injector 1 - Faulty ignition coil 1 - Fuel injector 1 harness is open or shorted - Fuel injector 1 circuit poor electrical connection - Ignition coil 1 harness is open or shorted - Ignition coil 1 circuit poor electrical connection - Insufficient cylinder 1 compression - Incorrect fuel pressure - Intake air leak.
