1997 Lumina intermitant stalling,starting probs fixed

I inadvertantly hit enter in my last attempt to enter this post..Here goes again...My usually reliable 1997 Lumina LS suddenly started stalling and would not always start up again..continued for a few days (good for a while then stall again) Had it towed to a neigbors small auto-shop and he determined that it was the ECM (engine control module)...He swapped in the ECM from another Malibu (same 3.1 engine) that he had in the shop at the time..and presto...stalling probs disappeared. Drove car home with no probs...(my fingers are crossed)
Cost $250 (CDN) for the new ECM and 130(CDN) for labor (2 hrs)...I hope this is indeed the fix....and not just an intermitant "up" period for the car. Will let you know if stalls again...

You may have lucked out. I had a Buick Regal that would totally conk out, I'd coast to the shoulder and restart it. It happened only when the car was fully warmed up, which makes sense as some of the components are heat sensitive with age and exposure to vibration.
