Hello there,

How many kms on this engine?

It is quite common for many cars to suffer from this condition.

Carbon buildup in the combustion chamber is one cause.

I would perform an upper cylinder clean with Subaru upper cylinder cleaner, the long route, spark plugs removed, long soak with the cleaner product etc.

Refer this to your mechanic.

If he has never done this, it will change his mind.

I do this periodically on my own and customers cars.

Hope this helps.

Gary
