At 10,000 feet you will loose 30% of your already anemic horsepower. The O2 sensor will correct the mixture once warmed and running. The biggest error I see with mountain climbing is waiting too long to down shift and keeping the accelerator floored trying to maintain speed. The worst thing for most gasoline engines is lugging. When are you lugging? If increased throttle does not result in increased speed, you are lugging the engine. Downshift, lift you foot and let the engine take the grade at 4,200 rpm instead of keeping it floored at 2,600 rpm in 4th. It is a short stroke engine designed to rev and it likes it. Dennis

Next month the Mrs and I will be driving through/over the Sierra Nevada mountains. Maybe up to 10,000 ft (3000m) elevation. How well does the 1.9l's ECU handle that thinner air? -- Mike "Rocket J Squirrel" Elliott 71 Type 2: the Wonderbus 84 Westfalia: Mellow Yellow ("The Electrical Banana") 74 Utility Trailer.
