Integra GS-R Idling problems HELPP

I've noticed lately that some days when idling the car idle's where it always has idled. but the past couple months some days it will dip down to half of where it usually idle's. Anyone know of why this is happening? i was thinking about possibly getting a grounding kit for the car but i'd rather get some input on this first before i start throwin money into it. Thanks~Steve

i kind of had the same issue.... my problem had to do with the fact that i swapped in a B16A into my 1990 Acura Integra GS (stock B18A).... still using the stock AC but the alternator from the B16.... whenever i would turn on my AC my idle would cut down to the point of nearly dying... i took it to a mechanic and he said that my alternator was completely wrecked so i had it rebuilt and now the problem is gone
