The car is 1998 s70 GLT, with 69000 miles.
I am experiencing random stalls and loss of power. When this started, I:
1) Had a fuel injector cleaning done
2) Replaced spark plugs, rotor, distributor cap, plug wires
…kept stalling/loss of power.
3) Replaced idle air control valve
As a result, I still experience either loss of power when at speed, or occasional drop in idle which sometimes results in a stall.
11 months ago, I had the mass air sensor replaced and vacuum leaks fixed. I don't know when the last fuel filter was put in (I'm the 3rd owner). As a note - I no longer run a K&N filter since having replaced the mass air sensor.
