My car is: 1997 Volvo 850 Turbo. I have been having some issues with it for over 4 months now. At first it would act like it wanted to shut off it would sputter and stuff. Now, if I drive less than 55mph, it will shut right off. It starts back up with no problem, but I will drive it for a mile or so and it shuts off again. Sometimes I can drive it for miles and it will be fine.

I currently have my MAF sensor disconnected, because I cannot even drive 100 foot without it shutting off. I have been driving without the MAF sensor connected for about 2 months now.

I was trying to figure out the problem when I noticed that these two hard plastic hoses, towards the bottom, they have c-clamps, and where the c-clamps are there is a softer material that is all shredded up and it is showing a metal filter looking thing. I think that maybe that could be part of the problem with my MAF sensor, not real sure though. I am going to try and post pictures.

I have wrote on the pictures what hoses I am talking about. This is a stock photo of another car I found on the internet, it is not mine, but the hoses are just like mine.

 

Unclamp those hoses and fix them. They are the intake and pressure hoses for your turbo charger and will cause huge drivability issues when not connected properly. Once they are fixed, plug your MAF back in and it should run much better!

 

If it continues to shut off after fixing these hoses I would concentrate on the fuel pump.

 

Fix that and your problem will be solved. the holes you see are between the air flow measurement and the engine, so air is leaking in and out downstream of where air flow is measured by the MAF.

If you go to ipdusa.com or fcpeuro.com and look at the air intake parts you'll see all those rubber hoses offered for sale.

 

After lots of searching and the answers provided in this thread I have found the part I was talking about. It is called "Intercooler Hose" as seen in the photo included with this reply.


Thank you all so much!


But now ....


I have been looking all over on youtube for a video that shows me how to replace the "Intercooler Hose" and I cannot find one anywhere.

Would you happen to know where I can find a video?

The big plastic hoses are fine, it is the intercooler hose that is attached to the plastic one that needs to be fixed.

I don't know how to do it, and I don't know what tools I may need, to get the job done.

 

There's not much to know so I'd be surprised if somebody did a video. Usually other projects require removal of the hoses so you can look at some other vids such as replacing the PCV to see if there's any reference to removing the "OTE" tube (over the engine). Mostly they are held on by band clamps and the plastic/metal tube parts have ridges to create a seal when pressed into the rubber hoses - so expect to have to pull/wiggle to separate after you remove the clamp. Last thing is you should also inspect your intercooler for any damage. that's the radiator like part - the idea is, when the turbo compresses the intake air it heats up, so the air is then routed via the hoses through the intercooler to drop the temperature before flowing into the engine. The system operates at anything from 1 to 1.5x atmosphere so any leaks in the hoses or the intercooler will throw off the metering of the air flow (and as such the control of the fuel mixture). In terms of tools, take a look - you probably need a phillips screw driver or torx bit for the clamps, a small socket set or small metric wrench set for the bracket nuts (10mm being the likely choice).

 

I will see what I can do. I am kind of new to all of this. My husband use to do all of this for me, but he passed away several years ago, now I am trying to learn all of this with the help of people like you, so thank you so much for your patience

 

Jacqueline, it is not very hard. Once you get the parts let us know and we can step you through it. BTW, I see you are from Michigan. Where at, as I was born and raised in Wayne.

 

I just ordered the part from eBay, but it does not come with the clamps. Also, I am from Ludington, Michigan, but I am currently living in Shelby, Michigan until July.

 

It should be held on with reusable hose clamps.

 

Thank you! The one clamp I am curious about is different than the big ones. It looks like you have to use a special tool to remove it. It is a very small clamp, about as big around as a nickel.

 

Thank you so much to all who replied. It seems that the "Intercooler hose" was the issue. My brother was kind enough to help me get it in place. It was not easy getting those two hoses together (tight fit). But, it is running much better.


Again, Thank you all soooooooooo much!

 

Glad we could help!
