Thread: HELP... My car has a weird SMELL if floored/boosted??

Gas smell: either running very rich or leaky injectors. Check spark plugs.
Rotten eggs: clogged cat
Burnt oil: rear valve cover is leaking on to rear exhaust manifold. Could be a fire hazard.
Sweet smell: Burning coolant, maybe lower intake manifold gasket, coolant elbow, etc. Check spark plugs.

Check all of your fluids for quality and fullness and pull your three front spark plugs to check them. Heck, show us a picture of them. Also, hold a mirror behind the engine to see if you've got an oil leak from the rear valve cover. Report back.
