Yesterday I go to a mech to recalibrate the steering and clear the Driving Assist Reduced and ESP error (this were brought on by a faulty battery. ) The car also had a check engine light on. Diagnosis detected two errors: cylinder 2 misfire and fuel too lean (it was at -0.8%). We tested the plugs and coils by interchanging with those from another cylinder but the error persisted in cylinder 2. The mech suggested it's mostly likely a piston problem.

After the mech was done with recalibration of the steering, I went okay to my destination. One hour later I start the car and there's rough jeering from the bonnet. The car losing power too. Engine often goes off on its own. Today I have cranked the engine twice but it goes off on its own.

What could be the issue? Please help
