from 87 octane to 91

[Kuruption]

Do i have to do anything special like clean out the fuel tank and line? I just used the predator turner and i got a check engine light... Im assuming that's do in part of not having the correct fuel in there. So my tank almost empty as it is (over 3 bucks a gallon ) can i just fill it with 91 octane or higher?
