Hi Mike,

What am I missing ?  How did tightening up your dipstick in the tube
cure the stumbling problem ?

The only change you could have made was seal up any vacuum leaks into
the engine compartment, but there should be a pretty good path into the
crankcase from the pipe that feeds fresh air into the PCV system.

I was wondering if you had figured out any explanation.

Alan ( will check, but does'nt recall having any donuts ) Cordeiro.
 P.S. does'nt have any stumbling problems either.
