hi all, i recently purchased a 1987 olds eighty eight from my dad.The car is in mint condition body wise and interior.The problem im having is stalling while in drive at a stop.My father had it to 3 different garages including "Myers Motors" dealership and the problem still remains.We had the following things done to it(the list to follow is new parts replaced)fuel filter,fuel pump,crank position sensor,idle sensor..the car wont stay running at a stop but is fine on highway.Could this have anything to do with torque converter or maybe idle sensor needing adjustment.Any help would be appreciated cause im really tired of spending money on needless replacements

This problem was solved.What i did was re-check the iac(a garage had put a brand new one in) and found that the mechanic had not put the gasket in which made the settting of the iac off. I reset it and no problem since.
