I just bought this 960 -96 B6304(S?) last week from a dealer and earlier today sitting in a line the engine almost died while running at a standstill. But it recovered from maybe 200rpm and warped to 2000rpm for a second. I thought no more about it but on my way home this evening the "lambda" light suddenly appeared on the left in the dash, I have no clue what this symbol means but a friend who understood some german (my 960-manual is on german) said it was something about engine electronics/control and that I should seek a volvo-mechanic as soon as possible.
I checked fuses and wireing that I could see in the enginecompartment but I con't not see anything abnormal.

Now the engine feels like its loosing power sometimes and almost cuts power completely. What could it be? I haven't much experience of this engine yet, just upgraded from a 760 -88.

And by the way, is it possible to pull the errorcodes by myself without special equipment/instruments? If so, where? (pictures if possible)
God damn I miss my Haynes service handbook I had to my 760.


I built a simple diod-resistor testlight for the B280F engine on my old 760, and I guess that on the 960 there should be some built-in system for checking errorcodes?

Any ideas? What have happened? Help!
