engine stall on idle
This happends once or twice a week ,but yesterday it happened 4 times it just shuts off on the red light ,so on the idle (never happened when car is in motion) rpm's are dropping down from 1000 and it seems like engine don't have enough fuel or air in the mixture,sometimes rpms dropping down and engine is almost stalling but it gets back spinning at 1500 2000 for the first 2 seconds or so then returns to 1000.It mostly happends right after stoping at the red light,when i push brakes ,right before stop rpms arer getting lower than 1000.
I'm trying to figure this out ,have new fuel filter to change ,but t most likely that engine don't have enought of air or it's pressure,there's sucking noize that my mechanic noticed when i took my car fo the checkup,maybe something wrong with MAF censor ,i'm not too familiar with saab engines and don't have repair manual ,so maybe you can help me figure it out. Thanks

So cleaned it up with carb cleaner ,it was pretty dirty,broke PVC nipple at the same time ,(thanks god that wasn't serious),when started engine it was idling perfectly,but on my way home engine stalled once when iwas on the red light ,so maybe i should look for pressure leak or something else

RE: engine stall on idle
Well while your PCV is broken you DO have a vacuum leak, however that should actually make the car rev higher... run a can of seafoam through the gas tank and see if anything changes. Also check your plugs...

seafoam is already there ,pvc nipple holds on crazy glue (still),new parts are about to come.
What i noticed is when i'm pressing the brake rpms going down in 2 times out of 5.Will take it to the mechanic this week will se what he'll say.
