SES until warm?

[ricochetbuell]

I changed my oil and removed an Edge Juice from my truck yesterday and everything was fine. Went to crank it this morning and have a ses light before and after it cranked. Shut it down popped the hood and checked everything out no luck. I decided to ease to work truck ran fine a little sluggish and almost sounded like the cackle was muffled after I got on the highway and the motor got warm it kind of bumped and the ses went off and picked up a little speed. Went to lunch today same thing so I sat and idled until the truck got warm tach bumped a little and light went off. Any suggestions?
