Subject:      Sticky AFM?
Content-Type: TEXT/PLAIN; charset=US-ASCII

I have a problem that I think might be a sticky AFM and need some ideas.

Symptoms: Total loss of engine power.  Engine stays running but engine
lights flicker because of the low power.  Pressing on the throttle does
absolutely nothing.

It is intermittant so I can't exactly test too many things.  It has
happened three times in the last week and each time the engine starts
running again fine after doing some meaningless fiddling with the engine.
It starts fine after turning the engine off and then back on as well.


My diagnosis (perhaps a completely unfounded one): AFM.
I think that either the flapper is sticky (although it didn't appear too
bad this morning when I opened it up) or else the signal between the AFM
and the ECU is bad.

Questions:
- How can I check the AFM and the electrical connections?  (Remember that
the problem is intermittant too).
- Any other ideas?

Thanks a ton,
Blake
