Did you check the card behind the right-right lights?  It's a small black
box that pops into the Idle Stabilizer wires.

Unpliug the box and pop it open with a screw driver.  It may have some burnt
components.

Best regards,
Shawn.

Subject: new engine / no cold idle

I have transplanted a 90 2.1 WBX with very low miles into my 91 Syncro.  It
runs strong, but will not idle.  It seems to surge a bit at the startup and
then completely stop after approx. 5-10 seconds if you do not hold the
throttle open.  I have checked all that I can think of.  I would appreciate
any advice as to where to begin again.......

TIA,
