Yes, the MAF is located just after the Air Filter box. Not sure if you have a secondary or not.

With WD40, I would check all vacuum and intake areas, Intake boot, throttle body etc. You don't need much but a short burst in one small area, waiting a short bit and moving on. If you find something, you will notice and RPM change while the engine is running at idle.

Cheers & Good Luck!
