Thanks for the link MPRESSION. I think it was a little over a year ago, that I brought the idling problem to the attention of the stealer and they did the following:
exact excerpts of the work they done:
"0000005 DIS/MODIC TROUBLE SHOOTING
"1214520 REPLACE PULSE SENSOR"
"112141748398 E34 O-RING"
I have no idea what these refer to, but it hasn't stopped the rough idling. I did replace the OEM spark plugs to Bosch Platinum +4s, and that seemed to minimize the rough idle, but it's still there once every blue moon.
