Default Help, help four error codes came up!

All of a sudden the CEL came on after the car started to haveidling problems and felt sluggish. I pulled the following codes: P0134, P1171, P0171 and P1174 on my S80 -99 T6 with 75,000 miles on it.

They all seem to point towards a faulty Mass Air Flow Sensor but after a little bit more research (reading previous posts) it perhaps can have something to do with the ETS and ETM? I read somewhere that there's a 10 years or 200,000 miles ETS warranty and it has been extended to even replace the throttle body, is that true?

Anyone got some thoughtsabout this? I would appreciate any help!!!

Thank you!

For the recall........

As for the MAF, 8$ at the part store for some cleaner is well worth spending 100+ to replace it.....

The Dealer will also check the engine vent system before replacing any parts.

Default Did you ever figure it out?

Did you ever figure out what was troubling your volvo? I have a 1999 T6 S80 with the same codes.

P1171 Bank 1
P1174 Bank 1
P0171 Bank 1

I was hoping I could deduce what is troubling my baby. She had a bad CVVT, I replaced it along with all 6 coils and new plugs. Then she ran great for 3 weeks.

Then, misfiring again and stuttering, smells awful out the exhaust and gas mileage plummeted. I cleaned the MAF, but didn't notice much of a difference.

Let me know if you have any ideas for me or if you solved your problem.
