Anyone know how to test an ets on a 2001 road king I keep fouling my spark plugs . I can put new ones in and it will run fine for about ten minutes or so them both plugs are black. Any help or ideas much appreciated

 

What's a ets on a 2001 road king ?

 

engine temp sensor. but the ets will not affect just one cylinder. look for something specific to that cyl. stuck injector comes to mind real quickly

 

Is it limp mode?



cheers

 

read it wrong, guess you're fouling both plugs. just swap in a new one, they're not that expensive suggest you make some other quick tests first. assume comp is ok and this just started. check all your grounds at all places and have you checked spark plug wires? they fail and cause too much resistance and missfires fuel pressure can also be an issue. too much or too little causes missfires. also did you check for any codes in ecm? is ck engine light flashing?

 

No codes showing , spark plug wires check good , grounds seem tight not sure ets is the right place to be looking with no codes but only thing that made since

 

What makes you think that it is the ETS? Try this post #22.

I know that the values are similar for your model.
