Hi all,


The patient: 1984 Vanagon 1.9L. 120K miles
Symptoms: Rough/no idle when cold. Motor will start and will idle at
approx 1000 rpms until I give it a little gas to move along. The idle
speed will drop to zero and "bounce" back to 800 or so (with attendant
screeching belts and blinking idiot lights) and typically die unless I
force a higher idle by keeping my foot on the gas. After warm-up (the
temp gauge moves off the peg to perhaps 1/4 up the range), the engine
will idle fine at approximately 1000 rpms. It will however, cyclically
slowly increase idle speed to approx 1300 rpms and then drop back to
1000.
Diagnosis?


Thanks in advance,


Kris S. Seago
