Unplug MAF, the engine will switch into using AFR tables. If it runs fine, replace the MAF, otherwise look for vacuum leaks.

That maf value is through the roof, assuming it was measured on idle?? The more info you provide the greater the chance is you'll solve this.

No! Go to fcp euro, pick an OEM replacement and buy that (on Amazon, or wherever you like). Volvo ECMs are very picky when it comes to MAF. Bosch ME7 only works with Bosch MAF, one part number fitted to that particular ECU.

Like previous speaker said, buy OEM when it comes to maf.

You can fix your car for $200, or $10 plus junkyard trip....

Or just light $87 on fire and still have a broken car.
