ok so let me get this straight ;
your sunroof stopped working because of a misfire which occurred because your brother put cheap gas in the car and the engine light came on because of the damp weather...are you still surprised no one responded to your post?I mean how often do you come across this type of a problem?

I suggest you do a more intense search on google about your issue and I'm sure you'll figure it out.I'd give you some links but its 11:30 pm
