Does anyone know why a 95 (crossover model with full OBD-2 computer) Jimmy would idle high after the battery was flattened and then boosted? The ECM isn't throwing codes. It sounds like it would if the EGR were stuck or an air line was popped off (in either case, this isn't the case). I assumed after a varied drive, the computer would correct the problem but as of yet it hasn't.
Anyone?
Thanks, Andrew.
