i think its the small speed sensor fitted on the back of the speedo, it sends the speed from the speedo to the ECU. it enables the ECU to know when to switch from the over run mode into idle mode. to check it, unplug ur injection ecu behind the bat. drive the car, if the stall goes then its most probably the speed sensor. should set u back abt 50usd to buy it, u can change it at home. the new part is better built as a fix for this issue.
