I don't know where you get that idea, but I've seen warped heads, exhaust manifolds burned almost with holes in them, valves with cracks in them, etc... all caused by a misfiring cylinders (bad plugs, cracked wires, weak spark, bad coils, bad points, or weak electronic ignition systems). Fuel cut is what manufacturers do because cutting ignition and still providing fuel is bad for the engine. Mazda, BMW, Dodge, Toyota, and Chevrolet/GM all have rev limiters that cut fuel - not ignition. -->Neil ------------------------------------------------------------------------------- Neil Bradley There'd be no more N'Sync if everyone had guns.
