If there is a vacuum leak the engine will rev up a bit when the WD40 is sprayed there. It gives the engine more fuel.
My GZ runs great, no missing or popping but it will only run 65 on level and drops to 60 or 55 quickly on a grade.

Be sure and check that tire pressure, and with your weight, I would run about 2 psi above the recommended pressure on the front

Good luck!
