It's a shame I only come here for bad news but yesterday after a (delightful) small trip (200kms) I notice my 2013 M13A jimny started losing power. Checked the oil and its okay, coolant has some spots in it but I have been offroading recently and putting off changing the coolant. Temps were fine all trip.
This morning I hooked up my obd2 and the P0303 (cylinder 3 misfire) fault code came up, as well as the check engine light on the dash.
Any questions on where to start and as to what it might be? If I blew a head gasket I will be selling my car soon...
Simplest thing first, check the spark plugs and leads. Then swap the coils round and see if the misfire moves with the associated coils. Next check the wiring to the coils though it will be obvious when you swap them if a connector is not seated or a wire is damaged.

Sent my jimny to the mechanic about a week ago and they confirmed bad sparks and leads and coils. Changed them for orignal nickel sparks, ok coils and ok leads as they were insanely expensive over here.
Arrived home today but the engine light is still on, OBD2 scanner now says all cylinders are misfiring with no other codes. I'll wait a bit more to see if it goes away but I'm already very worried. Any more leads??
Bit more info, 2013 Jimny (4all, as Im from Brazil) 140k on the clock.
