Each of two drives into altitude with our 2001 Sport recently we struggled to keep up with others in our group. The altitudes were 9900 and 8400. Was there a malfunctioning sensor, etc. that might have caused this, or just something we have to deal with by shifting to a lower gear, which we did?

I guess it's going to happen since the Sport is a naturally aspirated V6.

Yea that's just the nature of the beast due to the lack of oxygen at altitude. Kind of hassle but disconnecting the battery to promptly reset shift points and fuel trims should help but can't say if it would be noticeable. Same with making sure your air filter is clean, going to a lower octane (85 is common at higher altitudes, if that safe to do in these trucks?? Might want to check your owners manual) and keeping your tire pressures in check since it changes with altitude and temp. Probably wouldn't hurt to increase the pressure at higher altitudes than you would with normal driving at lower altitudes to decrease rolling resistance. Just don't want to inflate them to the point where they bulge in the middle (overinflated).

Thanks JK. Didn't think about disconnecting the battery, but had a clean filter and us 85 most of the time. Tire pressures were set to 30, so they're on the high side already. It was puzzling up there!

Not a problem. An aftermarket intake probably wouldn't hurt either.

Not a problem. An aftermarket intake probably wouldn't hurt either. No kidding, installing a short ram with cone filter really improves throttle response. |
