Is this an auto shop teacher? Because if it is you need a new teacher.

The timing is not adjustable on these motors, except by reprogramming the PCM. Sounds like one of your sensors is out of whack. Try testing the TPS, the MAP and the MAF.

You would get a better response to your problem by posting in the 4.3 engine section.
