SAI CEL now ISV?
So I got my car back together after a successful SAI flush (more on that in a different post) and took the car out for a spin. My car idled perfectly before the flush, but after getting about a mile from the house I pushed in the clutch and the car stalled. It continued to idle rough, or stall, on the way home when the clutch pedal was pushed in. ISV or did I miss something when I put the check value, air cleaner, and heat exchangers on that would cause that? I did double check that little vacuum hose behind the check value.
Thanks in advance

May have found the problem. I did disconnect the battery while doing the flush. I'll go drive a bit and let you'll know.

I've encountered that behavior when I've had the battery disconnected. I think the ECU needs to recalibrate. A 15+ minute drive solved it for me. If you're still idling rough & haven't cleaned the ISV, you might give that a try as well.

Well, while driving around on side roads for 20-30 minutes the car kept stalling. Thanks to this great place I had what every 993 owner should have in their glove box….a spare DME relay. I parked (actually stalled) under a street light, with nothing to lose I swapped out the relay and drove around for another 20 minutes without stalling once! She seems to be back to normal.
Thanks again RL!

Whenever you disconnect the battery the car will do that until the ECU recalibrates. The fact that you changed the relay and the problem went away may just be coincidence.
