Could use some help with a diagnoses problem with my saab. Have had some problems recently with the car dipping at idle but i think i narrowed that down my ICV valve which i cleaned up and reinstalled. Seemed to work ok and is good enough atleast it isn't stalling at idle. During that time i also changed my fuel filter and checked/cleaned my spark plugs. Seemed to work for a little while now and i must admit i was using some cheap fuel in the thing and after changing to a higher octane it really solved the problem, but i have also had a stalling problem after fillup that i think i diagnosed to a fuel bypass valve that i havent had the time to check. Now here is the big problem, two days ago i filled it up with highest octane i could(92) and had my usual sluggishness after fill up which i expected...drove about 30 miles and reached my destination with no problems. After leaving serious problems started trying to get the car rolling. When engaging the clutch in first gear the idle is all over the place and seems spiratic power like their is no fuel combusting and similar in second gear at low RPM. Now during start up the car is fine and idles great but after traveling and coming to a stop, in neutral, the idle takes a serious dip and the car is barely running im saying its down at 500 rpm if not less and seriously struggling. This seems like something new that isn't caused by the icv or the fuel bypass valve, could use some help here as im trying to make it home for mothers day.
