I just took my S90 out for a spin after I fixed the rad fan problem. All of a sudden, it started to idle at around 300 rpm and wouldn't accelerate. It would stall. I would start and it would be ok...then about a minute later...start doing the same thing. This happened a few times until I got it in the driveway...
Now it seems to idle ok...(Worried about taking it out again.)
I put a fuel pressure gauge on it and it shows around 37 psi while idling...
I suspect that the fuel filter has not been changed in ages...probably original fuel pump. (455,000 km on the car)
No codes popped up!
Thoughts?
