Back in the day, tip-in hesitation would lean toward bad accelerator pump, but now things are much more elctrical. Common causes of hesitation are an interruption in fuel, a fading IAB valve/motor, or TPS. Check those first. Also check the computer, it will provide tremendous help and steer you right to the root of the problem. In 2 years I've never had a problem I couldn't immediately identify and fix. Get into the habit of checking the computer every month and fix any problems that come up. It will save you some day, trust me.
Most problems nowadays with poor motor performance are electrical, not mechanical. Good luck, and email me if you have any specific questions. I have a really good book. deathblowbob@netzero.net
