The vehicle starts up fine and will accelerate when I shift into D or R just fine. However, sometimes when I'm driving, and I come to a stop it will accelerate very slowly. It basically will not move when I accelerate. The RPMs do move on the dash panel but there is very little movement from the vehicle. I've noticed that if I turn the vehicle off for a few seconds and start it back up it drives perfectly normal. The only code I've gotten is P0014, which I replaced but still having the same issue.

This sounds like it could be a fuel pump that is going bad, but the code says there is a problem with the camshaft sensor which could cause an issue as you have described. Here is the location of the sensor so you can check it out:

The error code P0014 on a 2004 Chevrolet Trailblazer refers to a problem with the exhaust camshaft position timing over-advanced or system performance on Bank 1.

Check out the images (below). Please let us know how it goes.
