I regularly drive from Phoenix (1500') up to the Flagstaff area (8000') and
notice no difference in performance form one location to the other. I have
driven the high route through Rocky Mtn. Nat'l Park @ around 13000' and
though my body wasn't working too very well (pant, pant), the van still ran
just fine.
This all with a 1.9 in an '85 Westy.
I'd start by looking at the O2 sensor.
