johnson 140 four stroke rough idle

johnson 140 four stroke 2003-2004 its been an exceptional motor until now. engine light comes on as soon as its cranked and idles a little rough and will cut out occassionally. ive tried swapping out the fuel filter thinkin it was just water in fuel,but thats not it…hoping its not something stupid electric…thoughts and tips appreciated

if the engine light is on, there is an issue with a sensor, or something making the sensor think its bad.
you need a mechanic with computer diagnostic ability to look it over

I had a lot of problems with mine also because of a bird nest.Point is If you don’t take it to Chris or Seels Marine STAY WITH IT.
