850 Fuel Injectors

Randy, I have been reading up on injectors today and it seems that they should be cleaned/checked at 50,000 miles and replaced at 100,000 miles. It is possible that the cleaner has shifted a minute speck of dirt into the nozzle area of the injector. Take them to your nearest Bosch dealer who should be able to clean and test them for you and tell you if they are approaching replacement time. The usual result of them getting close to "lifex" (life expiry is that performance and fuel consumption start to suffer.

Here in South Wales we just have some drizzle at the moment with expected highs of 8 - 9 degrees and dry for the next couple of days.

All the best, Peter.

Thanks guys for the info. I'm going to pursue both leads. Several months ago, I changed my normal procedure of filling up with 93 octane. I have since been putting mid-grade (89 octane) and today I filled up my nearly empty tank with 93 again and put in one more can of fuel additive. It seems like already there is an improvement. In the meantime I will take Peter's advice and get the injectors checked and also check my wire boots. Last summer I replaced the plugs, but did not put in a new set of leads... this has potential.

Thanks again for the prompt replies. I am also going to check the motor mounts as I have replaced several on my Volvos over the years.

Cheers, Randy
