Re: PCV Valve Retrofit - AES Motor (1997-2000)
I am driving across the U.S. in my 1995 Eurovan 5 MT. My mileage per gallon fluctuates: mostly over 20, but as high as 34 and as low as 17. I¡¯d say the van gets peckish at altitude and isn¡¯t keen

RMartin1962 - thank you for this great report.
How does one measure the "partial load/long term fuel trim" ? I have VCSD Lite (and am willing to upgrade to the paid version).

Macon, Don, and others, thank you all so much for joining the discussion!
It's nice to know I'm not alone, and maybe with more minds and more data, we can figure this out?

Re: Eurovan Gasoline Fumes when Hot & High - Recap
The idea that the EVAP system is malfunctioning is very logical and I'm not ruling it out, but I am leaning towards other explanations.
