TPI HELP

[George M. Dailey]

Peter jogged my memory. The dry manifold design of the TPI has a tendecy to
form carbon on and around the throttle body air valve. Grab an old pair of
underwear soaked with carb cleaner, wrapped around your finger, and 'goose'
the TB. This will remove some of the carbon build up. Try this before
fooling with the sensors.  Carb cleaner can be sprayed in the IAC valve
inlet port (with motor running) to clean it.

Keep hope alive!
