My 2018 Holden Barina is misfiring

Asked by Andrew

My 2018 Holden Barina is misfiring. It has a lack of power and is shuddering. I'm thinking the MAS needs cleaning. Is this easy to fix?

What make you think it’s the MAF (Mass Air Flow) sensor? If you’ve simply googled the symptoms and found a forum that suggests the MAF sensor, be very careful. These forums are not universally populated by people who have the first idea of what they’re talking about. True, some forums are great and wise, but simply pulling an answer out of a hat without even seeing the car is a road to nowhere in many cases.

It's also why the advice we’d have to give is to have the car looked at by a professional who will probably start by electronically scanning the car to see what fault codes have been logged by the computer. It’s possible the MAF sensor is, indeed, the problem, but it could also be about a thousand other things that need to be ruled out before you start spending money on new parts that may or may not solve your problem. The fact is, these symptoms could be anything from a dud spark plug to a loose wire, either of which would cost a lot less to fix than fitting a new MAF sensor.
