2001 S80 T6...appears to have Throttle Body issue yet Volvo not responding

[frankm]

Hello everyone.... a newbie here.

Mike F.....I caught you posts and noticed you are in Thornhill. I am
in Richmond Hill.

I have a 2001 S80 T6 with ~61,500 km and I am having symptoms, which I
believe based on other searches, is associated with the throttle body:

- rough almost groaning at times, when at idle
- air from HVAC fluctuates higher/lower, whether in drive or park
- tachometer at idle fluctuates
- lights dim
- car has even stalled on occasion

Volvo sees no fault errors when they hook up the car to the computer.
In addition, they have not been able to reproduce the "stalling" issue,
though all the other issues are quite obvious. Right now I am
extremely frustrated with Volvo since I feel as though they don't even
believe me. The car has stalled on several occasions with both my wife
and daughter in the car.

I would appreciate any suggestions anyome may have in getting Volvo's
attention with this issue. It seems it is falling on deaf ears.

The official count is 343, but there was also a volunteer who lost his life
aiding in the initial rescue efforts. And I will never forget them as
long as I live,
nor should any American.

Had the same issue, it even dimmed the lights when I pushed the window up/down button. All I had to do was replace the spark plugs. Not sure which one was doing it, but it did the trick. No more low idle!

What spark plugs did you replace? All of them?

a few things you can do to try and fix this issue. you do need to replace the spark plugs 1st. from here I would check and replace air filter. then from here, I would check every vaccum line and replace them. its a pain in the ass to do, but these cars are know for vaccum leaks. from here I would replace the Mass Air Flow Sensor. Mas air flow sensor does go bad and cause a bunch of issue with these cars. when you replace this, you must disconnect battery cables for 20-30 min. and step on brake for 30 -40 seconds to drain all battery current from main computer. this will assure that your MAF sensor with have a clean slate when it starts to perform. it will run rough for about 5-10 min, then begin to level off.. if this doesn't fix the issue. check dipstick tube for back pressure. some people use a balloon on the dipstick with engine running. it should I believe try to suck in the balloon. if it trys to inflate the balloon, you have some clogged oil lines. I replaced the oil trap and seals for that, and also dropped the oil pan, had the pan professionally cleaned , cleaned screen, and replace like 5 seals included dipstick seal. this seamed to fix the surging issues, even though I didn't have back pressure. I did at one point have stalling issues, and the light come on saying I had no oil pressure and to turn off car. I put 10w-40w oil and new filter after dropping pan (not an easy job). we actually cut some of the ends off the oil pan, just to be able to get it back in. it was a nightmare trying to get it out. I would suggest trimming the frame lip alittle to be able to get the pan out.
oil changes are a must and, must be done more than normal ( do not use synthetic oil). I spent about $2500.00 getting my car to finally run correctly., also replaced seals on the turbo return lines. lots of work, lots of money spent. replaced the turbo pipes on top that have some sort of sensor (heater) that burn the oil so it doesn't go through the turbo. I replaced all the spark plugs, oil filler cap (which usually leak), replaced gas cap, which also usually go bad. gas doors usually break at the plastic part. most stuff you can find on ebay, or europarts.com, ipdusa.com, and there are a few others. if you have any questions contact me at [email protected]
