1995 Saab 900S engine cutting off after drop in RPMs

\015 Hi,After I have the car up to about 3000 RPMs and I get to a stoplight, I push the clutch in and as the RPMs fall to a idle, sometimes the car will cut off completely. It happens not only when just pulling out of a parking lot, but also after driving the car for an hour and coming to a stop. \015 Posted / edited by AnonymousUser on : 15-01-2018

Check the IAC valve and all vacuum lines. This link will take you to a DIY site showing where the valve is located on the naturally aspirated 4 cylinder Saab and how to clean it. If any vac lines look suspicious (dried, cracked or otherwise) replace all that you can get to. Vac leaks are notoriuos for causing poor drivability and stalling. Finally, clean out your throttle body and throttle plate and do a tune up if it has been a while (i.e. put in some new plugs, a new distributor rotor, a new air filter, etc.).

My 1999 Grand AM SE 2,4 has a fine idle when slowing down ahead of a stop-sign/trafick light and idles on about 550-600 rpms, but as soon as the speed drops below about 5 mph, the rpm drops to 350-400 rpms and the engine shakes (there is a bent part inside the engine that is causing this, I think after talking to a mechanic and I also might have a bad engine mount or two, but the engine runs perfectly smooth above 500 rpms. I Have tried to change all mechanical parts, like airmass etc, but its

This is caused by the bypass valve - when dropping below 800rpm it should open, letting more air in, to keep the rpm up. In your case it doesn't. Take the car back to the shop and have the codes read, find out if the cause why the valve isn't opening ... 1999 Pontiac Grand Am GT

Low idle Yesterday I stopped at a traffic signal and the engine slowed down slightly under 500 rpms. I bought this car new and it has always idled at 900 rpms. The air conditioner clutch started disengaging and engaging. I pressed on the gas to bring the engine rpm up to 900 and the engine ran fine. As long as the engine is running at 900 rpms and above everything works correctly.

2004 Saturn Ion. At times the engine runs too fast at start (3k rpms) or will sometimes kick into that while driving. Other times while driving in slow/stop and go traffic the rpms drop low to 500 idle becomes rough and engine stalls. At the time of the engine dropping power like lights dim. No codes are being given, nor any dashlights except at stall. The dealer is stumped, we have replaced the software on the car's computer and replaced the throttle sensor. Still no change.

Engine dies I have a 2004 Linclon LS six clydr with 43000 miles which operates very well except on occasion the engine will "die" and rpms will drop but within a second the problem is gone and the rpms come back to normal.
