Bruce..that was 87-89 Chevy Celebrity's w/2.8 MPFI. That was a recall. 
Apparently something was screwey when you disconnected the battery. The car 
would never relearn the idle strategy, apparently due to a bug...surprised?? 
Anyway, trhe fix was a new calpak, unplug the MAF and apply a decal over the 
MAF relay cover. I remember doing a few dozen of them on the line.
