ECMlink Diagnostic Mode Stalling

[LarryJoe]

Recently I've been having trouble with the car stalling when coming to a stop. I looked at others peoples threads and they all said I need to adjust the BISS screw. So I went into ECMLink with the car up to temp and idling fine but everytime I ground the timing and diagnostic pin together the car just dies. So if the car dies everytime I put it in diagnostic mode how am I supposed to adjust the BISS properly?

UPDATE: Got a new throttle body, isc sensor, and tps sensor from throttlebodys.com. Made sure to adjust my tps correctly. Did a good BLT and fixed every leak. Car still won't idle correctly in learn mode to set the BISS. What to check next?

With ECMLink, the factory service manual procedure of grounding the timing and diagnostic pins should be ignored. DO NOT ground the timing and diagnostic pins to set the idle speed. Just adjust the BISS screw so that the ISCPosition reads 30 with the engine completely warmed up.

I wasn't aware of this. But don't you need to have the vehicle in learn mode so that the ISC centers itself? Just trying to understand.
