Shakes or Wobbles problem
2005 GMC Canyon Four Wheel Drive Automatic 63000 miles

The truck vibrates when idling at a red light but does not vibrate when driving I think it may be something in the fuel injector maybe idk though hopefully you can help thanks. There is no check engine light on either

Only at idle, I would look into the IAC (idle air control) its located on the throttlebody. Possible a piece of carbon is causing the solenoid to stick. Clean it out with some carb clean, and see if that helps.
