i just adjusted my valves on my renegade tonight(i used the shop manual for reference,and it wasnt my first time doing valves on an atv)but now my engine has a high idle and the check engine light just came on.i let the engine cool for a few hours and re-checked the gaps and they all seem perfect i set my intake to .0040 and exhaust to .0060. it should be the mean value of there recommended settings.

sounds like a vacuum line off or a sensor not connected of something like that ,look around and see if you forgot to reconnect something.:2cent:

found it there was a loose plug to the fuel injector.funny thing is i didnt touch that wire when i was doing the valves.thanks for the advice i rechecked everything after reading your post.
