Double D

Ive got a 92 honda accord lx and am baffled as to what might be my problem. My check engine light comes on when key is turn to the "II" position and hear the clicks of the PGM-FI relay but sometimes the check engine light fails to go out and the car will either start but immediatly stall or idle like crap aswell as run but when i turn the engine off after started or just double stroke the ignition the light turns off and runs fine? Ive been looking for the ground location but cannot find it to make sure i am making a good ground some advice or the ground location would be excellent.
