    If you haven't changed the spark plugs for 25,000 miles or so, replace them with new Volvo plugs. Other than that you'll need to have the codes pulled from the engine control module and perform the troubleshooting for the codes retrieved.

    If you've replaced the plugs and still have the same problem, then replace the ignition leads too. This worked on my 1998 V40. Be careful you connect the correct lead to the correct plug.
