Okay... Back from a long day out. Good news, though: the culprit was indeed the throttle hose (located under the throttle body cover). As you all suspected, it was rotted out and just went in the last month. Actually, MIJ, you were right on the money as the tech informed me that the "knock" I heard ...

MIJ & Oceanman -
Just went out to check this out and unfortunately the hex bolt on the cover is stripped (damnit!). The guys at the dealership have tools to deal with this so I'll have them remove the bolt and cover first tomarrow. If this is the problem it'll save me lots of $$$ in the long run ...

You're right on the money - the hose popped off where the air enters the airbox. I'm glad you've made this point for me because I was pretty sure myself that this would have little consequence other than a tiny loss of power. As a matter of fact (as a funny sidenote) the last time I was at ...

It's been some time since I've been around here and situation now dictates my need to seek the collective wisdom of the forum. Anyway, its nice to see matthewsvolvosite acknowledged at FCPgroton.com.

Anywho... I have encountered a slight problem with my 850 ...

Most likely you hear the motor running but there is nothing to actuate the movement of the seat-back, or in other words your cable is no longer working. Apparently, it's fairly common to have to replace the cable.
You could pull some DTCs from the diagnostic box under the hood. There is a procedure ...

The motor described by CarVolvo is actually the seat-back recline motor, located inside the seat-back. The motor that you are looking for is #3, which operates seat-cushion height at the rear. This motor is located under the seat. Grab a flashlight and take a look under there. You'll see ...

I have the same exact problem with my 95 850. Everything works except the height adj at the rear of seat cushion. I retrieved DTCs that the wires to motors 1 & 3 are unplugged (which confused me a bit more since motor 1 is functioning as it should). I studied all the related documents provided in ...

hmmm...
Called the dealer again today to try to get somewhere with this and tech I spoke to said the sensor would be located on the driver's side up to 6" back from the air dam, all the way to the wall, so to speak. I looked and looked and looked and didn't find anything. The only thing I found was ...

Sorry I missed your question earlier, Mc909....
Like Bill stated, the link is available at the top of the forum. If you have any trouble finding it or downloading it let someone know so we can help you out.

All this talk of Serp belt causing the noise makes me wonder...

I'm replacing my timing ...

Good advice, MrReilly - from what I've read so far this is seriously one of the most important factors for being successful. It's important for me to hear this, too, because if something doesn't seem to work I often times leave it alone for fear of breaking or damaging it. This project will take a ...
