2008 Holden Barina Pricing and Specs

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.

A manual car that jumps out of gear is usually a case of a worn gearbox. As the internals and gear selectors wear over time, they become loose, allowing the vehicle to jump into neutral.

The first check would be to see that the external linkage to the gearbox (a cable in the Barina’s case) is correctly adjusted and not about to fall apart. If that’s the case, you might find that the selector is not fully engaging each gear, and that’s why it’s jumping out of that gear. But beyond that, the problem is likely to be caused by wear inside the mechanical bits of the transmission.

The first thing to check is the fuse. The location of the fuses panel will be shown in the owner’s manual; that should also show which fuse is the one for the instrument panel.
