my dad drives a 90 da9 automatic .....when he comes up on a stop .....it idles really low and sometimes dies .....any suggestions to what i should adjust? ....help!.....thanks in advance.......oh and i did search already ...no real answer ...thanks once again...

 

check your plugs wires cap rotor and how old is the fuel filter, if all this items are in good shape adjust the idle and set the timing.
If the idle is searching after all this you may have a bad IAC

 

thanks
