My idle is very low. maybe 500 RPM's. I would like to raise the RPM so less warm up is required to start driving without restarting everytime I come to a stop sign. Thank you, Jeff

here is porsche's (or is that VW?) own tech document re the AAV on L jets.
issued in 76 when the cars were only 1-2 years old.

(document from the marvel of the marvelous Jeff Bowlsby website).

its not issued in relation to D jet cars, at that time L jet was termed AFC injection.

not a strong start from cold when new and it just gets worse with age.
where are we now, thats right, half a fricken century down the track. (IMG:style_emoticons/default/biggrin.gif) (IMG:style_emoticons/default/beerchug.gif) (IMG:style_emoticons/default/beer.gif)

I actually wish we had a high idle circuit for warm up like the D-jets and modern cars have today. The vehicle would warm up faster in my opinion. But I guess Bosch knew better with the early AFC haha.
