Default 80k Service? and Throttle Position Sensor?

got an e-mail from the dealer who sold me my 2005 Colorado that my truck was due for its 80,000 mile service. did a little searching on the web and even read my owner's manual and can find NOTHING about an 80,000 mile service. is it real, or something they made up to pilfer my pockets? if it is real, what does it involve?

Also, getting a constant check engine light, so took it to Advance Auto and they said it's a throttle position sensor/idle speed too low. is this something an average do-it-yourself backyard mechanic could handle, or should I just bite the bullet and give 'er to a pro? any ideas how much it should cost?

thanks for any help you can give. :D

These trucks have timing chains (no belt) that last the life of the motor, they don't need valve adjustments, etc. So... they only really need fluid changes, spark plugs, and serptentine belts throughout the life of the motor.

If you regularly change your oil and change your plugs/other fluids every 50k then no... you don't have to do anything special unless something breaks. Before you replace the TBS I'd de-carb the throttlebody and re-set the codes.

Replacing the TPS is a 5 minute procedure. Just remember to disconnect the battery before you switch it out. Good luck!!

it does exist, but its integrated into the throttle body. i've yet to see one bad. remove throttle body and clean thoroughly and you will be good to go.

It was clean as a whistle when I took it of yesterday to look at it. I swapped out a TB of an 09 canyon and still have the same problems.

Isn't there a throttle position sensor/module attached to the gas pedal?

So cleaning the throttle body fixed your problem?
