[s-cars] Rough Idle Still?

[Mark Strangways]

Did you reset the ECU after you changed the bits?
Was your ECU specifically coded to make use of the RS2 bits ?

Gents,
Ok changed out my RS2 Injectors and RS2 MAF back to stock units and replaced
my O2 sensor this weekend.  I did this due to the fact that the car was
running very rich, as suspected...which destroyed my O2 sensor...causing a
rough idle and CEL.
Replacing the above did fix my "upper" sporadic idle and CEL issue however
now I am getting a low idle/stalling problem.  My ISV seems to be OK and is
clean but this stalling problem is curious.

Any ideas? Bad O2 Sensor (Borg-Warner Part#OS702)? As no Bosch were
available at NAPA, Checker, or AutoZone? Output tests on ISV "sound" good,
as I can hear the valve open and close.  Perhaps Fouled plugs due to rich
mixture could cause stalling?  Bad stock injector after re-install?

Thx

cp
