Hi,
I just joined. I am a bit of a car collector especially older cars.......which my wife hates. In addition to a 2003 Jaguar XJ8 Vanden Plas, Acura TL 2006 Manual, I just got a Volvo S70 GLT 1998 model year. It's a one-owner vehicle. I just noticed today it stalls when I really try to accelerate. This happens after driving for around 10 minutes. I also notice it stalls and then starts up, almost as if it's about to run out of gas. Fuel pump or fuel pump relay maybe? Do the Turbos on these go out with these symptoms? The mileage on this car is 142,000

 

While it sounds like it could either be the fuel pump or relay, I have to ask.....is the check engine light on and are there any stored codes? If so, read them and see what they say. As for the problem itself, I would suggest first off you do a full tune up to get a good starting point. This includes Air filter, fuel filter, spark plugs (Volvo OEM or NGK seem to work best) spark plug wires, distributor cap and rotor. See if any of that helps to begin with, and then we can go from there..

 

Thanks for the extremely useful information 👍
