Volvo S80 Problem Report

Volvo S80 Rough Idle, Stalling and Check Engine Light On

(9 reports)

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 -
When I start my car the engine over throttles and spikes to higher rpms before settling down after rumbling for a couple of seconds. normal driving doesn't seem to be affected but starting it varies every time. -
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 -
I HAVE THE SAME PROBLEM IT IS ACTUALLY THE ETM OR ETC I THINK THE ELECTRONIC TROTTLE MODULE,IF YOU THE ENGINE OIL IS FILLED BEYOND THE LEVEL IT SHOULD BE IT SNEAKS IN TO THE ETM AND THEN THE PLATE STRTS MISSING(IT BECOME OILY) AND THEN YOUR PROBLEM STARTS SO ITS BETTER TO REPLACE IT OR HAVE IT CLEANNED YOU COULD DO IT YOURSELF IF YOU KNOW HOW -
I have had it replaced at least 4 times already -
