This needs to be repeated a few times in order to blow out any carbon deposits that may build in the upper combustion chamber.
Has anyone heard about this???
There must be less abusive ways to clean out carbon deposits. How does a tranny spinning at high RPM help clear out carbon deposits in an engine? The pistons only move as fast as you are accelerating. What you should do is find a long stretch of the QEW (
) at night and do go WOT in your Northstar powered Bonneville.
A WOT run will clear out carbon build ups on the valves and plugs.
Shifting gears and revving the hell out of your car will hurt your expensive 4T80E.
