Hi all,
MY 98' S70 T5 automatic stalls while driving, and dies when I stop. It usually starts right back, then dies again. If I rev it up it doesnt die, but then I have to cram it in drive to make it go. It doesn't do it consistantly mostly when its fully warmed up and driven for a while. Also it keeps fouling the sparks plugs somehow?(no oil on them just like its burning them) First I put boush platinums in it this is about whem the trouble started. So I went and got some plugs from the volvo dealer, didn't fix it. Since then I've replace the ditrubuter rotor, rotor cap, plug wires all with the best (oem)
It didnt do it right after a replaced yesterday, I it drove about thirty minutes. I thought yeah problem solved, got in it today and not even five minutes later stalling, get to a stop light and it dies :( I'm replacing the fuel filter today maybe that'll do it. Anyway sorry for the long post but I wanted to be detailed as possible. Oh yeah and the air pump is dead that wouldn't cause this would it? Thanks for your time and help.

I had the same problem on my 940 (except the plugs weren't fouled). It finally got to the point after a few weeks that it would turn over but not start. It ended up being the crank sensor that was causing the problem.

delivery problem and its overrich! Any black smoke out the pipe when it starts to die? Also hows your gas mileage? Hows the air filter? Any check engine light codes?

Thanks for your response! It has no black smoke, as far as gas mileage I havn't driven it much since it started doing this. It has a few month old cone filter on. Only code I'm getting is the secondary air system one. Maybe I should take the cone filter off? Changed the fuel filter and it still does it. Its like it doesn't want to go then it takes off or dies one.

Ok I think I may have found something the fan never comes on. Is there any way I can bypass its control module and see if it come on?
