Re: 850 T5 runs fine, then won't start for a week.

Does it refuse to start for a week, and then just run fine again? Or did it stop running a week ago and has not started since? (i.e. is it an intermittent problem, or did it just fail a week ago and he hasn't figured out what it is yet?) Before throwing an ECU at it, (like the other guy just threw s...

Re: 850T - Intermittent stumble/very rough running

Roger..one of the most bizarre episodes of vacuum leak troubleshooting happened to me on my T5 Cause...completely rotted purge vacuum hose under the intake manifold, which splits to a T ( one side to snorkel for vacuum under boost, the other side to purge valve, the rotted part provides purge vacuu...

Re: 850T - Intermittent stumble/very rough running

Yes...BUT. '95 turbo have vacuum controlled FPR on fuel rail. That said.... It should have 43.5 psi at 1st prime without starting the engine -around 35 at idle -and again 43.5 psi at full throttle It doesn't have constant 43.5 all the time like M4.4 cars. Good point, thanks for keeping me straight!...

Re: 850T - Intermittent stumble/very rough running

I measured the fuel pressure at a nice, solid 2.5 bar, 37 psi. It fluctuated nicely when I revved the engine, and the regulator responded to the vacuum fluctuation. I subsequently checked the diagnostics, and realized that the spec is actually for 3.0 bar, 43.5 psi. Hmmm...

Re: 850T - Intermittent stumble/very rough running

Hi erikv11, thanks for the input! - My first thought is a torn/cracked intercooler hose that doesn't always leak but when it does, way too much unmetered air gets in. Especially if the problem is most common at idle. I'll check, but I don't think this is likely. When I took it for a test drive after...

850T - Intermittent stumble/very rough running

I'm having trouble with an intermittent stumble on my '95 854T. It happened today, although it's happened before, too. Today, I ran for 15 miles at 70mph on the interstate. As I rolled up the exit ramp I could hear the engine start to run rough. As I pulled up to the light, it ran rough and stumbled...

Re: Aisin 50/51SN Problem between 3th and 4th gear

I just went through this on my V70, same transmission. You should search the site for V70 transmission issues, you'll find lots of good discussion. To summarize though, there are a number of steps to take, keep going down the list until you fix your issue. They are: Replace the transmission fluid, r...

Re: 2011 XC90 V8 Anti skid and brake service light on

I would read the codes and see what has been triggering the messages. Probably worth lifting it up, pulling off the wheels, and inspecting, to see if you can see anything notably incorrect - there may be a mechanical issues that doesn't explicitly set a code. Let us know what you find. Good luck! Ro...

Re: Turning signal and wipers switch problem - mostly when it rains

I've replaced my turn signal stalk, and IIRC it was pretty straightforward and easy. With that many miles, I would not be surprised to learn you also needed replacement.

Re: Cell Phone Mount for 03-06 XC90 that doesn't suck

Can you tell us which cell phone mount you used? I have one I want to use, and it appears to have a ball of similar dimensions, but I like how your ball screwed in to the switch. I'd like to know make/model of the mount, I might do a hybrid installation. Thanks!
