I think on my tiptronic 2003 996tt the idle seems a bit low... when a/c is on its around 700 rpm. and if I come to a quick stop sometimes it feels like its going to stall.... is there a simple adjustment to bring the idle up 100 to 200 rpm?

 

what are your volts at when the a/c is on?

 

a little under 14 volts... car idles at 600 700 rpm a little I think

 

what kind of intake do you have?

My guess would be your maf is bad, or the throttle body

 

having someone look at in a few days... thanks guys

 

Mine will drop when you first turn on the A/C but recovers to around 800 RPM (just like normal) very quickly.
