Yea I'd clean up my MAF sensor (aftermarket filters you oil like k&n can coat the sensors with oil and make them run weird) and run a can of seafoam through my gas/vacuum lines (if high mileage).

Also like 88 said check that module I caught mine when I first read about it, I sanded the oxidization off of it then painted it all black to help resist corroding anymore, good prevention if not the issue at least.
I have a friend who has driven his truck with a cracked module for like 2yrs now and I don't know how he hasn't gotten stranded yet!

Tune up if ya haven't done that in a long time wouldn't hurt either but don't think it'd cause odd symptoms like that.
