Hello!

I checked TPS voltage on my K1100. On ignition on the voltage is 3,6V - in the window. Yet after engine is started, the voltage drops to 3,2V. That is something strange to me. Can any one tell if it is normal, or TPS should be set on running engine, because vacuum change butterflies position (close them)?

Best regards,

A digital voltmeter hookup between pin 1 and 4 of TPS connector.

Usually I use this method to setup the TPS: http://www.largiader.com/articles/motronic.html with the engine not running.
