I'm not going to be of much help here but I read other postings that say
this is a symptom of either the Catalytic converter being cogged or the O2
sensor being fouled by crud or just burned out.
The things I'd look for are loose injector ground wire (two white wires
under the driver side intake air tubes) or an injector plug that isn't
making good contact at the injector.
If you need a catalytic converter I've got a good unit for the 80 model CA
only for $25.00 + UPS. I'll send pictures if you need them.
Also I've got that O2 sender for $12.00 + UPS if you need one.
Both parts are used but working.
Matter of fact I've got the whole 80-83 CA only exhaust system if you want
to stock up on spare parts at a good price before they get away.

Subject: '80 air-cooled power loss
I have a 1980 air-cooled vanagon w/ 2.0 F.I. non-calif. model, M/T
Items recently replaced:
fuel tank
fuel pump
fuel filter
replaced breather/vacuum lines
charged battery/cleaned connections
checked timing - 7.5 btdc
plugs look good - gap .028
air filter
cap & rotor look good
brakes all around
new clutch master & slave cylinder
replaced intake boot - afm to throttle body
symptoms:
van idles and starts up great, revs up really good and returns to idle.
Engine sounds good and runs good, no missing.
When I drive the van and put the engine under load I have to really rev it
up to move. Under low and mid range
rpm it bucks and coughs, but at high range rpm it drives really well. Is
this more likely an ignition problem or
a vacuum problem. I've looked repeatedly for any missing vacuum lines and
leaks. Timing retards when I rev up motor.
Runs great when sitting, runs poor when driving.
Where should I be looking?
thanks, Jamie Foust
