I was wondering....I installed the famous capacitor (22mfd)and ground strap
at the AFM to cure the "acceleration hesitation" problem that I've had since
I bought the van.  The fix worked, but I noticed that the variable resistor
is slowly wearing through the "carbon" track.  I know that this will
eventually give me problems.  Is there anyway this can be repaired at home?
I noticed that the resistor board is glued in place.  Is there a source for
these?  PO was "playing" with the spring tension and have had to increase it
4 notches to run correctly.  Are there any procedures to check this at
home???  Maybe with the O2 sensor output?  Of course the Bentley manual
completely ignores the innards of the AFM....probably one of those
"non-serviceable" items.  Thanks in advanced!!
