Hi:
My 2001 9-5 (2.3t) has developed a "stumble" on idle after running the car for a few minutes after start up. Basically, when the engine is still not fully warmed up, if I come to a light, the rpms will drop for a fraction of a second, the car will almost die, and then jump back up and idle normally. Although, the last few times it has actually stalled, but I am able to put it in park, immediately restart it and drive normally after that.
Just this morning, it stalled after making a bit of a "screaching sound" (similar to when you try to start the car when it's already running and you get that starter grind noise), and once again, I put it in park, restarted it and drove off.
Plugs are pretty new, fuel filter is too, no CEL's to speak of. I originally thought it might be bad gas because I filled up at a rural gas station... but I have since filled up with two tanks of Shell V-Power, and now it started doing this again.
Any ideas what might be causing this? Any help would be appreciated.
