dont just worry about how you drive, check you tire pressure, air filter, if you werent leaving tomorrow ide say do a full sea foam treatment. (depending on how old many miles you have) but you can just do a quick one of adding a can of sea foam to a full tank of gas, and clean your injectors out with some sea foam deep creep. but when you have time i highly recommend doing a full sea foam treatment. if your interested here is a good guide.

just dont do it from the hose directly on the brake boost like that says, do it after the little plastic separator/deregulator(?) or whatever the piece is that separates the 2 hoses between the brake booster and IM

that wont help you so much for tomorrow but will in the long run.
