[s-cars] ECS Light and Bad Idling/Stalling - '92S4

[Mike Bishoff]

Hi All - In recent days our '92S4 has been stalling and idling poorly. The
ECS Warning light is coming on, so it seems obvious there's probably an ECS
component that needs work. I found in the manual how to check codes, but it
doesn't provide much in terms on interpreting. A couple of questions:
 
1.	I don't have the little jumper wire specified in the owner's manual.
Looks like there are four connectors involved and wonder if I can
manufacture a simple jumper that emulates this factory jumper.
2.	Who has the ECS warning light interpretation codes?
3.	Is there a typical ECS component that could be at fault? 
4.	Any possibility of loose connectors on a sensor causing the problem?
5.	If I can track someone down with a VAG, will it tell what's going
on?
 
Thanks!
