1995 940 Location of MAF?

I have a 1995 Volvo 940. Having issues with it idling rough and acceleration from 1200 - 1800 is spotty and rough. Cleaned the Throttle Body. Not sure if this was EVER done. It was nasty. Ran great for 1 day and then acting up again. Replaced the Throttle Position Sensor. No change. Still bad.

Reading in this forum, I see similar problems to mine. We've eliminated the throttle body and tps. So now I'm thinking it is the MAF. I've replaced an MAF on my son's 1999 Bonneville, so I know what that one looked like.

I'm stumped on where the MAF is on this Volvo. I look up the part and see images that do not match anything in the air flow area. When I pulled the biggest hose from the air filter chamber I see a part that looks like the item pictured here: http://www.ebay.com/itm/Volvo-740-760-9 ... 1294724950

The item above IS the MAF ... right? Can anyone tell me if I've found the right part?

Thanks.

Your own link shows this as an air intake sensor.

If you have the IAT sensor then you have Bendix/Siemens fuel system and you have no MAF sensor with that system on that car.

Could the IAT sensor cause the same issues as the MAF? The issues I describe above? Could I clean this IAT sensor with the same cleaner for MAFs?

Okay - I was confused by the description on eBay that says "Volvo 740 760 940 AIR TEMPERATURE SENSOR REGINA / AIR MASS METER AMM MAF FLOW"
