[T3] Stalling after 15 minutes on the Interstate!

[Jeremy Menzies]

I had this problem once when I adjusted the idle speed before the car was fully warmed up.  After a freeway run, the oil gets hot enough to fully close the Aux. Air Regulator, which will cause the idle to drop lower than normal if it's been set after only short in-town driving.  When it happened, I just rechecked the idle speed and bumped it back up to normal.  I did have my lights, wipers, radio, and possibly the fan on when I stalled in the squareback, so I'm sure that played a part in it.  I'd do another freeway run to get things nice and hot and then recheck your idle speed.  You could also plug the AAR hose w/o the freeway run and set it that way but I think the heat up method is probably better.

Aside from that one time it stalled completely, I do notice that the idle will drop pretty low for a brief moment after I've driven on the freeway and come to a stop (like at the end of the ramp), sometimes causing the oil light to flicker unless I rest my foot on the gas.  I've heard this is 'normal' from a few people, so I don't worry too much about it and just keep the RPMs up a tiny more when it does happen to boost the pressure.

My two cents,

> My 1971 Fastback w/fuel injection has been running great, mostly short trips to work, etc.  Yesterday I decided to run up the Interstate about 8 to 10 miles to visit my son.  Car was performing good, I was driving at 60 to 65 mph, no problems.  I exited off the Interstate into the town where my son lives and every time I had to stop the engine would die.  At first it didn't want to start but I found that if I put the pedal to the floor it would start back up and would run until I stopped again.  It acts and feels like the engine if starving for fuel.
