Hello,
One more thing, buy a Bentley's repair manual. pay the $30.90 price for a new one on ebay--if you don't see it, check back later.
the air box thermostat serves 2 purposes. it is there for cold days.
1) it opens a flap on cold days to allow heat to enter the engine which helps the car run. once the engine is warmed up the heat from the engine will expand the a/b thermostat, which will close the flap.
2) recycles exhaust fumes.
test the air box therm in boiling water to see if it expands. if it does, it's ok, if nothing, get a new one or just tape the flap closed.
a non-working a/b thermostat will allow hot air from the engine to enter through to the amm (air mass meter) which has a needle inside to measure air flow. the hot engine air will cause the titanium needle to fail prematurely, which in turn cause your car to run poorly. the ecu unit that monitors your amm will try to adjust your injection system to your failed amm. ie your car will run badly.
great deal on the 93 wagon. i'm looking for a 93 wagon with no rust.
