Thanks for the link, very informative. Even if that isn't the direct cause of my turbo issue, at 170K miles it makes sense to fix it.

thanks in advance for reading this....My 95 850 Turbo, 170K miles has this pattern with the turbo:

1. very little boost, can hardly get it into the white, no punch.

2. hard codes are 4-3-5 "heated oxygen sensor, slow response" and 4-4-3 "TWC efficiency".

3. After I reset the codes - and ...

Your answer was pretty funny turbol, "please ensure that you foot is completely off of the brake pedal" , heh. Actually, it was a bit of an ID Ten T error - : on my 850, the brake switch clips into a metal frame and is held there by plastic prongs. The retracting switch itself is held against the ...

95 850 turbo. 167K miles.
This evening my neighbor knocked on my door and told me my brake lights were on, which was a surprise since my car was shut off and the light switch was also off! I wound up pulling the fuse until I can look tomorrow. The only thing I can even guess is a stuck relay ...

:D
It is help like I got here that makes it easy to donate another $25.00 to the cause, which I just did. I've been a fan of this site for quite awhile, I know it is expensive to keep it up and running and I also know it is a bargin for me to get help here rather than pay a dealer. Now to the ...

Lee,

Bosch and the codes are: 414,443, and 435 mostly. Plugs changed a couple years ago, perhaps longer. Wires before that, 4 years or so.

Hello. Thanks for the site - I'm a user and supporter with this issue:
My car starts and runs fine, but under strong acceleration, as in when I peg the turbo needle, it chugs, sputters, stumbles and recovers only when I reduce the gas. It seems more prominent at higher speeds, say jumping on it at ...

The car is a 2000, convertible, soft top. 89,000 miles. The adhesive has come loose all across the top of the glass rear window - currently held in place with towels. :-)
Not a permanent solution. Two local shops have declined to work on a Volvo, and we are scared of the $ at the dealer. What would ...

I appreciate the critique you guys - and, hopefully next time I'll have time to research a solution before I spend more than I need to.

This is a report on a problem that has been solved, just in case it might help someone else. About a month ago, my 95/850 turbo w/145k miles started hesitating a low speeds and actually quit a few times but started up again right away. A little disconcerting. :evil: I got a code of "misfire in ...
