I have an 05 road king police, when I get on the throttle hard, or at high rpm's the check engine light comes on and stays on till I come off it or slow way down. Also it has less power these days. What can the problem be.

 

The orange check engine light concerns emissions, the show stopper is the red oil pressure light.

 

Should have a code stored. Find out what it is.

 

ck code

 

What did you find out to be the problem. I just changed the fuel filter which had a hole in the line, changed plugs, cleaned air filter and now have the light come on when pulling hard or cranking on the throtle.
