MISAR System

Adrian · 01-11-2007, 10:58 AM

I am new to the Oldsmobile forum.

My daily driver and running resto project is a 1978 Toronado XS. The Toro still has the computer controlled EST ignition system. Love the car and the powerful yet efficient 403.

I am looking for the EST Coolant Temperature Sensor, which helps govern the spark timing. The AC Delco site has the wrong part number (shows a normal single prong temp switch). The part I am looking for is a two prong unit, anyone have a correct part number or source?

Thanks
