I know these trucks aren't supposed to be fast but mine seems unreasonably slow. In the city I can live with it but going up to the mountains it is pedal to the metal going over passes with engine screaming at 4K rpm and 55-60mph at most. Is that normal? Can anyone else in Colorado comment?

 

Aerodynamics of a refrigerator, coupled with the power of a ride on lawn mower, and voila - Disco. Our trucks excel at crossing rivers and driving through jungles with the sure handedness of a East German massuese. Highways are like fat chicks for them - a sometimes necessary evil to be carefully traversed incognito without any pep or gusto, and then jumped off of as quickly as possible so a real trail can be properly enjoyed and ridden hard.

 

I understand, but when I see a cargo van go screaming past me with similar aerodimanics and probably a similar engine I begine to feel like something isn't right. It would be great if others could post on how their trucks behave going up I70.

 

come on guys....


when was your last tune up? what about 02 sensors? airfilter? fuel filter?

what size tires are you running... is the car on 20's

 

Probably the best quote ever........

 

The truck is an 02. Completely stock. 70k miles on the engine, fresh heads, good compression, magnecor wires, a bunch of other new stuff, doesn't leak a drop of anything, runs great, no CEL codes. It feels OK driving it in Denver at 5280 feet but up in the mountains it just sucks. It wears me out driving it up hill.

 

so the plugs are fresh or not? what about the 02's ... what about your exhaust cats?

 

this quote definitely one ups the old standard mopeds and fat chicks quote !

DiscoArt........if you are convinced that everything is in a good state of tune......i'ts possible that the altitude itself is zapping you......I have heard from several who travel in high altitudes frequently that on certain vehicles it becomes neccessarry to have the ecu "re-mapped " as the original calibrations weren't enough for the application. Is there a good Rover shop nearby who might be able to assist you ?

 

You have a problem. What mountain road specifically are you talking about? I run up I-70 from the 470 and can hold 65MPH at around 3200 RPM's are so.
What gas are you using, when was it last tuned with wires, what air pressure in your tires?

 

Plugs are fresh. My cats are original with 150k miles. They do rattle a bit when cold but the truck just passed emmisions with flying colors. I would like to hear from other high altitude drivers before I go out and spend $800 on new cats.
