Subject:Re: Throttle Valve Switch - Lesson Learned
From:Dennis Haynes

The switch and cam has been updated to provide a more positve activation on
both sides. The full throttle enrichment is both for max power and to keep
things cooler to avoid melting pistons and burning valves. On the 1.9L
enignes one must becarefull not to switch the plug for the switch and
auxillary air regulator. Doing this will instantly destroy the switch and
the engine will think it is always closed giving the massive stumble or
shutdown of idle.
