Hesitates? Bucks? Dont' get me started.....   < grin >

Did this symptom start suddenly or has it been re-occuring over time?

Did you recently purchased this Vanagon?

It takes time, but pick a test route, use this same route every time you
test your rig. Make note of engine temp at start and finish and note where
hesitation happens. Try to duplicate this issue.

I would check other things first, but if you suspect the AFM......

Cleaning the resistive strip is an easy place to start. I used 99%
Isopropyl and Q-tips. And with a magnifying lens, you can inspect the
resistive strip for excessive wear. Take your time removing the plastic
cover. There are spots you can lever it off. Just work your way around bit
by bit. It is likely best to work on this part with air cleaner-AFM removed
from the vehicle.

Clean the OEM adhesive from cover and AFM body well. I found that a smear
of silicone along outside surfaces where these parts meet was sufficient to
re-secure the cover. That way I was sure no excess silicone boogers would
end up inside.
