[T3] AAR Resolved, and some questions about idle.


So I have the AAR more or less sorted out- it  closes nearly completely
when 12V is applied to it, and opens as it cools down. Tough thing is
that it doesn't close 100%- there's always some suction, even on a warm
engine (that is, idling for 20 minutes, I can't drive it since it's not
registered yet). However, when I put my thumb over the hose, RPMs drop
to 5-600. So fully sealed is probably not a correct state of affairs.

My idle now stays around a range of 1100-1200 and fluctuates, and when I
accelerate RPM dips a little and then throttles upwards. Both these
things don't seem normal to me. The former, should I adjust the idle air
bypass to get it down to 950 RPM (it's an Auto) since it seems like I've
reached the right point with my AAR? The fluctuation seems strange to
me- is that much fluctuation normal? I would almost think that there's a
vacuum leak. As for the dipping during acceleration, it almost seems
like the throttle valve isn't doing its job of sending the extra
impulses immediately to the injectors, but I can very clearly hear the
injectors fire when the car is stopped and I move the throttle.

I'm trying to sort out the idle so I can adjust the timing properly. I
checked the dwell after I adjusted it by feeler gauge- I'm at a dwell
angle of 44 deg, which is a pretty good start- I'm going to try to get
it to the recommended 50 deg.
