Why is it that when i rev up my engine, the rpms come down very slowly?

Does this have anything to do with the brake fluid that my engine is still trying to burn off due to a leaky master cylinder?

heavy ass flywheel keeps the inertia up

I'd try some wd-40 on the throttle body, around the spring and the actuator.

well about 40lbs of rotation inertia is the reason the flywheel is 26lbs and the pressure plate and clutch is another 15lbs easy that alot of weight to slow down after letting off the throtle

But, before any of this brake fluid got in my engine the rpms would go down pretty quick when i let off throttle. now they go down kinda slugish.

didn't you say in another thread that you had a boost leak? my other car would be slow to drop revs while it had a boost leak

Yeah i have a nasty boost leak. i have a ripped up orange rubber gasket from the stock pipe to the turbo. i can hear the boost leak from inside teh car.

^^That would affect why my revs come down slower then ussual?

How did brake fluid get in your engine???

My mastercylinder seal broke so it leaked into the brake booster. and from the booster into teh intake manifold through the vacuum hose.

But, is a boost leak a reason for my engine's revs to come down slower?
