Subject:Resolved: Vanagon GL 90 2.1L engine unexpectedly stalls while driving

Thank you everyone for your info, tips, and suggestions.  While replacing the spark plugs, I checked the compression of each cylinder.  While they are all low (110-120 psi), cylinder one was definitely too low (0).  I checked the pushrods and re-seated the one that felt like it wasn't quite in there.  I also put the old cap/rotor back on just in case.  After no startings at all a few times, and wondering why my spark plug wire to cylinder 1 was so tight, I got the wires connected right and she started up just fine. Did a quick fill/one person "bleed" of the coolant system.  The brakes were making some funny noise (2 months of disuse maybe?)  So I turned back from a test drive and got a little hesitation coming back up the slight hill to my house.  The idle is also seemingly a little rough and giving a ~30 Hz vibration.  Ah well, she seems to be holding her seal, so the next step is to send off the injectors for cleaning, replace the plug wires, maybe replace the air flow meter ($$$, but I can see deep tracks in the circuit and ohmmeter jumps when testing), make sure I have the right cap/rotor in there and get those brakes looked at.  Thanks again!
