Dear vanagon List Members:

My 83.5 Wasserboxer runs better than ever during the 60,000 miles I have
owned her.

Yet, the MPG has been declining over the last two months - down from 18 mpg
to 11.5 mpg. No fuel leaks. new Plugs, rotor and distributor cap. Recent
fuel,  air filter and pump.

New Oxy sensor.

My catalytic converter is empty of any catalyst and the muffler has been
cleaned out of all catalytic debris. There is a bit more power and cooler
running engine with a "throaty" exhaust note.

Ignition tuned 3 times in the last 3 months.

Exhaust stinks with partially burned fuel at idle.

Got any Ideas before I pull the trigger0?

Captain Meno.
