Re: Boost = Hesitation

The experts will jump onboard soon and tell you what to do. But I think the fuel pressure is a good place to start. You can disconnect the vacuum line to the fuel pressure regulator and see if there is gas in it. That would indicate a bad regulator. Also, you could put a fuel pressure gauge on the fuel rail and see how it acts. I believe during wide open throttle the fuel pump is supposed to kick into high gear. There is also a possibility of a clogged cat converter.
