Hi there,

I work for Holden/Opel, so I'll suggest a few things.

Your engine is a C22SE or C22SEL or Y22SE?

The timing belt is very important on your engine, how old is the belt?

I have seen timing belts fitted and not timed correctly, gives low power at low engine speed.

I have done many timing belts that transform the car back to near original performance.

The other part of the equation is carbon buildup in the cylinder head and injector flow/spray pattern.

We use a combustion chamber cleaning product (Subaru makes a good product) that cleans the majority of the carbon out.

Hope this helps.

Gary
