If all is working well, the O2 sensor will adjust the mixture as needed. Keep in mind that any normally aspirated engine will lose approximately 3% of it's power for each 1,000 feet of elevation. This is due to the reduced atmospheric pressure reducing cylinder capacity. My motor home with the Ford V-10 also struggles at these altitudes. Dennis

I routinely drive my van at elevations ranging from 5,000-14,000 feet here in Colorado. Above about 8,000 feet i experience loss of power such that I am only able to maintain about 30 mph while keeping the engine floored in second gear. I know its a crime but i routinely drive my van with my foot to the floor for a half hour or longer while going uphill in second gear (auto tranny). So my question is are there any adjustments I can make to have a better high elevation driving experience? Any Colorado listees out there that can tell me if they get better or worse performance on some of Colorado's steep/high highways (ie I-70)? Going east up to the eisenhower tunnel on I-70 my max speed is about 30 MPH (second gear, foot to the floor, 2.1L, AT). Thanks, Andrew Fox 86 Westy Ft. Collins CO |
