What is causing low idle on my 2004 gmc canyon

SOURCE: 2004 GMC truck

MAY BE A VACUME LINE IS NOT HOOKED UP RIGHT

SOURCE: Need to program a new Key Pod for 2004 GMC Canyon

the only way to reprogram a key fob is to go to the dealer

SOURCE: 2006 Canyon 4cyl has extremely low idle.

Could be:

• A vacuum leak
• An air restriction in the intake air path or exhuast
• A faulty positive crankcase ventilation (PCV) valve
• Damaged/failed/dirty throttle body
• Internal engine problem
• Failed PCM (powertrain control module)
  

I say back to the shop if its a real problem, if at all to just clear the code to see if it comes back. That code is just an informational code. Just says what the car is doing :\ . My first guess would be a vacuum leak somewhere followed by a throttle body issue.

Testimonial: "This is a bit late but the problem was a very dirty throttle body. I cleaned it up and all systems go. Thanx, Tewksindahat"

SOURCE: idle keeps dropping below 500 in 2004 gmc canyon

either have the throttle body serviced or replace the IAC Motor. Idle Air Control Motor.

Testimonial: "very helpful "
