Accelerator Won't Press '00 Silverado

[jflitcraft]

On occasion when I go to pull away the accelerator will not press in. I have to almost stomp on it before it will depress. I have gotten into the habit of checking it before I start the engine to avoid sounding as if I'm revving. What could be causing this? Any feedback would be appreciated...thanks!

Carbon buildup in the throttle body

 

Clean throttle body.

Yup, give the throttle a good cleaning to get rid of all the Carbon...Very common.

Thanks, I'll have to give that a try.

If a cleaning doesn't clear it up, there was a TSB on this problem and the fix was adjusting the throttle blade, adding a plug to a hole in the blade, and changing the PCV valve to a fixed orifice one. Had to do this to the '00 I used to have.
