I have a 2004 Canyon, 178,xxx miles since new. If you start getting low idle/ check engine light with "low idle speed" code after 30k miles or so, clean the throttle valve assembly. I clean mine every 50k. Carbon buildup in the assembly changes the position of the air valve at idle and throws the idle circuit off. You need a flat blade screwdriver, a 1/4 in. rachet with 6 in. extension, a 10 mm socket, a can of throttlebody cleaner, and a paper towel. Remove the aircleaner top (3 snaps), the cleaner to intake pipe (2 hoseclamps), the oil vapor chamber (big plastic box on top of engine, 2 bolts and a vent hose). this leaves the throttle assembly with 4 bolts and a wire connector. Remove and clean (wipe, don't just spray) the passageway thoroughly, making sure you open the valve with your fingers and clean the seating area. Re-assemble. iIt takes 25-35 minutes and 5 bucks; not even worth calling the dealer for. If you're going to own a truck, you should be able to do some of this stuff for yourself; you can't expect the dealers to wipe your butt for you. If you want that kind of service, buy a BMW or Mercedes- the pricetag will reflect your right to have the ashtray emptied for you on demand. On Tires, I burn a set a year - figured out they had the wrong alignment specs from the factory on the second set- a good shop is one where they know how to adjust the specs to make the alignment right; my guy made his own adjustments and I haven't had an issue since.

Replying to: puregreen (Jan 20, 2009 1:29 pm) With respect to the tire/alignment discussions, I decided to put my truck on the alignment rack, since it hasn't been on one since it was a couple of days old. All that was required was a slight toe adjustment, as the caster/camber were OK. The truck always drove well, once I got the OE General tires off of it, and was still doing so. However, after 4 years to "settle in", I wanted to check things once again.

I have an 07 Colorado 4 cylinder, 4wd. I've had no problems with the engine, altho the lack of low end torque is annoying. Shoulda bought the 4.10 rear end. With regards to alignment, the truck always tended to wander a little, so I finally got off my lazy hind end and took it in for a check. Man, what a difference. Guess GM doesn't do the greatest job aligning them. The tow in was way off. I suspect it's been that way right along. I also had them put some new shocks on it, which also made a big difference. I intend to add a rear sway bar. In 07 this was not even an option.
