Which temperatures?
The recent temperatures outside were around 30F or as low as 7F. The temperature when the car starts behaving like it's got a vac leak is 173.8F.
I data logged a recent trip to Radford VA when it happened and this is what I have:
(I adjusted the idle to be high so I wouldn't stall out--when the symptoms occur the car idles at about 1200-1500rpm. When the symptoms are not there the car idles at 2000-2500rpm)
At 3478RPM I see:
7.2 Lbs/min
3.0 inHg
AFM Air Temp is 34.2F
Intake Air Temp is 42.1F
Injector P/W is 8.73ms
NB O2 is 0.03 Volts
Coolant Temp 173.8F
I can pull some of the logs I've taken of the car during the symptoms if it would help.
I'm waiting on a garage to open up before I do any more testing.
