1) Checking operation of the O2 is good. Also check to make sure that there is 12V on the white wires from the harness and that there is continuity on the white ones going to the o2 sensor. It could also be the turbo bypass valve. If it does not hold vacuum, it will not open at the appropriate time and stall the engine. Does it happen when you accelerate then depress the clutch? classic TBV failure. http://216.78.173.190/turbo_folder/hootervalve.htm 2) you probably disturbed the sender connector, clean and try again. (other side of tank from pump) 3) bleed brakes again. Procedure is a bit 'non standard'. Bleed fronts normally (Press pedal release fitting) the rears require a slight pedal depression to engage ABS pump while the fitting is open. Some have suggested RF, LF, then rears. Do a search on www.saabnet.com C900BB on ABS and brakes for more info. 4) power door locks is either the control unit or the switch in the driver's door. http://216.78.173.190/electrical_system_folder/c900doorlocwir.htm Good luck, KeithG "Scott Morneau" <smorneaunopsamphia.net> wrote in message news:dafj7.886$QG5.976298nopsam1.news.adelphia.net... > I have a 1993 Saab 900T .
