what kind of motor? come sense would say bouncing idle check alt and batt volt and grounds. Then cells etc etc.. blah blah .. Funny though a guy on my other forum was having bouncing idle issues on his sr cause of excess blow by (crank case press.). He blocked off his IACV, took the T of the valve cover and did a oil catch setup just one line from v. cover to can and other end of can has a breather. This should help get some better crank case ventilation.
I would also try replacing your IACV.
