About failing AMMs ....

Just in case you're not aware -- the most common cause of AMM failure is prolonged exposure to overheated air caused by a stuck airbox (the air filter housing) thermostat that continues to direct heated air (from the exhaust manifold, via the foil duct) to the AMM instead of the alternate, cool airway from the duct in front of the radiator.
I would inspect that thermostat, and even better (my personal preference*) do something to ensure that it never ducts hot air -- your AMM could last forever this way, IMHO.

* I've personally used a dremel to literally cut out the whole flapper mechanism, and then seal the hot air opening with some "cap". From the outside, it appears (if you leave the foil duct in place) normal by any inspection short of opening the box (a real pain, and something state inspectors won't do).
Other folks have replaced the thermostat with a dowel that keeps the flapper closed against the hot air opening.
In any case, don't trust the thermostat.
