Problem Description and Possible Solution
During the diagnosis of the symptoms the technician may pull diagnostic codes from the Engine Control Module that point to a lean air/fuel mixture. If no vacuum leaks are found, then the mass air flow sensor (MAF) is often the cause.
Replacement of the MAF will be needed, along with a reset of the Engine Control Module and erasing of the diagnostic trouble codes.

Erratic idle with stalling engine on deceleration. Have replaced ABS module, cleaned the electronic throttle module, now need a mass air flow sensor? Problem is still happening
We did replace the Mass Air Flow and continue to have problems with idle. I have researched and found that later models also have this problem with a recall. I have spoken with the National Traffic Highway Safety Administration and filed a complaint with them. They will investigate for a recall of the Mass Air Flow sensor and are accumulation information pertinent to the complaint from other 2005 Volvo owners. Please contact them for filing a complaint if this is happening to you. It only took a few minutes of my time and they were very professional. This is the contact info. http://www.nhtsa.gov/Contact
