Hi Tim,

Petrol or Diesel?

Sounds like restricted fuel supply to me, how long since last fuel filter change?

Hi Gary It's a petrol engine, and it has been 2 1/2 years since the last fuel filter change

Hi Tim,

I would replace the fuel filter, then reassess.

While the fuel filter is off, blow through from the inlet side into a container to see how well the filter flows.

You may know before a test drive whether the filter is the cause.

It could also be a fuel pump.
