Terrible idling problem!

Asked by Sep 20, 2016 at 05:37 PM about the 1999 Audi A4 2.8 Quattro

Question type: Maintenance & Repair

My car will start but eventually stall out if you are not pressing the accelerator.
My RPM is very low, I've just replaced the TB. Not sure what the problem may
be. I also have a few vacuum cords that were un hooked when i purchased the
car. As well as two plugs that has nothing to be plugged into. Please help,
anything is welcomed.

get a vacuum diagram and make the vacuum lines go to the right places and that should fix the problem and the plugs might be for an automated timing light

Do you know where i can find a reliable vacuum diagram?
