I think your compression is fine - the valve adjustment accuracy could cause that much variation. You describe a classic exhaust leak sound - often it sounds like a valve click. The exhaust leaks really need fixed to get an accurate CO adjustment. Once the CO is correct a hesitation is usually fuel related -i.e. fuel pressure regulator related or a sticky throttle plate, the idle speed regulator is not turning off, vacuum leaks, etc. Harold McElraft - 3354 --- In dmcnews@xxxxxxxxxxxxxxx, Travis Graham <tgraham@...> wrote: > > Hello again, > > The last time I checked-in, I had discovered that all of my fuel > injectors failed the bench test.
