Help needed...please

I'm having problems with my beloved Volvo V70 classic 2000MY

It seems to be that when I'm at around 1500 rpm say in 3rd gear I get a slight surging .... its difficult to explain but its like as if its "hunting" / "misfire" once you put your foot down its fine, it tends to happen when its under load going up a slight incline...

The vehicle has a "white spot etm fitted..

Plugs are Denso.. which have done around 12000 miles... due to change them anyway...

The car runs fine for 90% of the time and Ive found the plugs to be ok and have had no issues before

Thanks in advance

The spark plugs have to be suspects in this. We had a not-dissimilar problem with our S70, and the issues went away with new plugs, even though the old ones weren't that long in the tooth.

Another possibility is the need for a clean up of the throttle body.

The next things on the list would be the air and fuel filters.

I guess then you could start considering the expensive possibilities - coil packs, ETM etc etc, but I think I'd suggest addressing the cheap and easy basic first.

Cheers
