Can you fix a misfiring cylinder?
Inspect the spark plugs for signs of damage. Once you’ve determined which cylinder is misfiring, disconnect the plug wire going into that cylinder’s spark plug. Use a spark plug socket to remove the plug so you can get a good look at it. If the spark plug is just old, replacing it may solve the problem.

Why did my 99 Volvo V70 not start?

Can a Volvo be driven with regular unleaded fuel?

What kind of gas does a 05 V70 use?
Our ’05 V70 with 2.4 (non turbo) has been doing fine burning regular (87 octane) gas. It was a demonstrator/loaner that was purchased about 6 weeks ago and I’ve only pumped regular, so I can’t really make a comparison. As long as it doesn’t knock and continues to get about 24 mpg for daily commuting I’ll stick with regular.
