Mass Air Flow (MAF) Senor, Throttle Body, or Both bad????? V70-XC70 1999

A week ago the V70 stalled and died on my wife. NOT a good thing!

Found that the plastic nipple that controls the flapper for the pre-heat hose hot air had broken off and was most likely pulling nothing but hot engine air into the MAF and throttle body.

Repaired that, but stalling and stumbling persisted.

Did a little research on the web, forum, and with my mechanic.

Unhooked MAF and car seemed to run ok with out it attached so at first I assumed bad MAF. I also removed throttle body and cleaned it out as it was nasty inside.

Once done, I started it up and it died. I unhooked the MAF and it took a few tries but it started up and ran.

This morning I drove it and my wife drove it and it stalled as well for both of us.

So which component is bad, MAF, throttle body or both? If it is the throttle body, is it covered by the recall that replaced for FREE all the ETM's for 1999 to 2002 up to 10 years after purchase? My car is a 1998, but is closer to 1999 as it was built in April of 1998 so near the end of the 1998 year run.

If it is not covered, just so I get this right, I need to purchase a new ETM, roughly $700 from FCP and then still go to the dealership for a software upgrade. Is this correct.

Please advise as I need to get this car fixed and back on the road ASAP.

Thanks,

Matt
