"Check Engine" light

Mystery: A guy put an amp and sub in my '89 RS. When
I drove it - after about 5 minutes the "check engine" light
blinked on and off at irregular intervals.
A week later, I still have the problem. Engine seems to be
running ok. At 2500 RPM light blinks on 1 second, off one second,
etc. Any ideas????
