My volvo 940 keeps cutting out and the garage can't work out what the problem is. Are there any volvo owners out there who can suggest what the problem might be. It's had a service and fuel filter change etc.

Take it back to where you had the the service and fuel filter done, Sounds like the filter has got air in it and needs bleeding

If you're air filter is extra dirty, it's a good idea to change it. Beyond that, the modifications become a little more complex. You can purchase a high flow air intake system, but I'm unsure how much it helps with performance. Another thing you can do is remove the warm air intake hose from the airbox. This is a hose that runs from the exaust manifold to the airbox, so that your car doesn't have to breath cold air when temperatures drop outside. It helps with emissions, but hurts performance. A lot of people disconnect these hoses, and then reconnect them when they have the car smogged. Sometimes people remove the catalyitic converter from the exaust system, helping breathability, but again, keep in mind it is illegal and you'll have to attach it again to ever hope to pass smog. A better, but more complex project would be to get a new turbo exaust installed, which is 2.5" rather than 2.0". Finally, if you're looking for more performance, always make sure the timing is within spec and your oxygen sensor has been replaced, those can really kill power if malfunctioning.
Well its nothing to do with this! But it is nice.

Thank you for the suggestions. It has a new air filter and the fuel filter was fitted yesterday to try and sort out the problem. It didn't. The performance on the car is very good until it cuts out. Then I have to wait for a while before it starts again. Someone has now suggested replacing the fuel pump relay. Dunno whether this will work.

Could someone with a grudge have stuck a potato up your exhaust pipe?
Alternatively, book it into Ringmer Service Centre, where they are very clever and have never failed to diagnose a problem on any of my cars, even when other garages have been beaten.

I use Ringmer Service Centre and agree with ACT's post - they are great!

Yah I always use Ringmer Service Centre to diagnose my problem, usually a spud up the exhaust pipe. No worries though, a good ole push gets it shifted.
Works every time.

One of the most common causes of intermittant starting/running in Volvo 740/940 is the Radio Suppression Relay, it provides
an earth return path for the Fuel Injectors. This very often develops bad joints, it can be opened and re-soldered if you
are able to do it, otherwise it will need to be replaced this is very easy to do yourself.
If you have a search around matthewsvolvosite.com you will find lots of useful information, search for radio+suppression+relay, I can send you a diagram showing the location of the relay, but it will need to be via email, let me know if this would help.

Thanks volvo man. I'll have a look at the website. Yes, please send the diagram - firstname.lastname@example.org. Thanks again.
