You Could possibly take your foot off the accelerator pedal.

Or turn the engine off

i'd try replacing the mass air flow meter before stripping it down to do the pistons, but maybe thats just me being lazy

That'll be an air leak then. Most common for coming loose is the thick plastic hose at the back of the bay on the drivers side next to the brake fluid reservoir
