RepairPal Certified shops can diagnose and repair your 2008 Volvo XC70. They provide transparent pricing with a minimum 12-month or 12,000-mile warranty on repairs and services.
These codes are fairly vague and caused by several electronic components. It could range from a front o2 sensor to a clogged air filter to trouble with the fuel system. I would take it to a reputable mechanic to have him run diagnostics to narrow the problem down.
