1999 Accord dies if idleing when fan shuts off

I need HELP!! I just changed the spark plugs, cap, rotor, wires & oxygen
sensor due to the rough running when first taking off & the check engine
light on. Runs better now, but, the check engine light is still on & while
the engine is idleing, if the electric cooling fans kick on, when they shut
off the engine will too, dies just like the key was shut off. ANY HELP, OR
GOOD ADVICE????

Thanks.

The check engine light is on because the ECU detected a fault. So the first thing to do is read the code stored in the ECU. Then reset the ECU and see if the check engine light comes on. When the check engine light is on, the ECU is in default mode which means that many of the inputs that makes the car run good are ignored. Autozone, I hear, will hook-up a reader to determine the stored codes. When you have that info, come back here and tell us what you found.
