If the car is a 1999 or newer, you could have problems with the electronic throttle, but it can set codes if it malfunctions. The 1999 V70 had a cable-operated throttle.
About your recent problem, unplugging the air flow sensor suggests you may have an air leak between the sensor and the throttle. That is common, as these cars have a lot of plumbing between the turbo and the throttle. If any of the rubber parts fail, then the air flow measurement will be wrong. There cold be a problem with the sensor itself too, but you can check for leaks first.
