I have same problem with a 1987 900S non-turbo with over 200K miles. Replacing throttle deceleration spring helped with stalls when slowing between shifts. Still stalls and hunts at idle when cold. New AIC valve helped some. Also set AMM to 380 ohms, new NGK plugs, new Bosch O2 sensor, Bougicord plug wires, and wire loom hangers. Check engine light works but stays off. Engine lacks power below 2200 rpm. Funny thing is that this car gives 34 mpg at 65 mph cruising and passed Ohio E-Check emissions test handily.
