Basically it's an air leak that bypasses the throttle There isn't much of a procedure to it, IIRC. You can unscrew it, look at it and lubricate the moving parts, that might help for some time. Then you want to lubricate it again, preferably with oil with greater viscosity so that the lubrication won't wear off so quickly. When mine (in a 900/-91) was dying, I finally ordered a second-hand AIC valve from a junkyard that collects wrecked Saabs. It cost me maybe 20 euros a couple of years ago: it's a similar valve but from a 9000 actually. :) Has worked splendidly since that, wouldn't consider too much repairing on it. br, S
