Mike,
Hum...
That thread is postulating that a TPS with a dirty potentiometer will send errant data to the ignitor. Disconnecting such a deviant TPS would alleviate the errant data at the minor expense of loss of timing advance during low load (part throttle) situations.
The key is errant data to the computer and the thread says this issue effects only the 270 cranks, intermittently as well.
Who would have thought that the TPS would fail in a way to send errant data to the computer? As opposed to sending either correct data or no data.
