i have a 89 saab 900 non turbo. the trouble started as i was driving down the road, now i am trying to find out how to fix it. you can only get it to start up by pushing on the gas some, wont start without the gas. if you let off the gas it will stall, or maybe idle for a few seconds rough then stall. i heard of somthing called the aic. i do not know where its located or what it is. the thing between the airbox and throttle body with the plug in which i think is the mass air sensor thing? i dont know what the problem is. it has a new cold start sensor and fuel pressure regulator on it because we thought they were the problems. any help ?

It definitely sounds like the AIC isn't working properly:confused:

When you push the gas pedal on a fuel-injected car like the SAAB 900, you're not squirting fuel into the engine like with the old carbureted cars--you're adding extra air. Adding the right amount of extra air is the AIC valve's job.

The AIC is about the size of a soda can, attached to the head just in front of the fuel rail. It has hoses going from the side and the bottom, and an electrical connector on top. Try removing it and flushing it out with WD-40. If this doesn't help, try another one from a junkyard; one from 1988 to 1990 will fit.
