Having these exact symptoms. Have replaced everything else, problem has only gotten worse, so I'm hoping this is the cause.
Started with just a slightly rough idle but then stalled while running but in park. Kept stalling no matter the gear unless I pushed the gas pedal and kept the RPMs above 1000. Seems worse when it is first started but still has trouble with a really hard idle even after warming up. It does have a bad thermostat that I'm getting replaced but that has been an issue for a while and it hasn't caused any problems so I don't see how it can be related. So far, I have no idea what could be the cause but I am going to see a mechanic in the morning that specializes in European cars. Last mechanic I went to said he thought it was the throttle body but wants me to see the specialist to be sure.
