Hello All, I've become caretaker to kind of an interesting Volvo wagon. It has until just recently been a very easy-to-drive sort of car. Lots of double-takes, too.
After warm up:
-the car experiences a fair degree of surge at idle from 900 down to 300 or so -- Possible too lean?
-fuel pressure 25-27 psi (Auto-Meter electric off the BBK regulator)
Question- What should I see pressure-wise for this set-up?
Thanks, Jeff
