[DML] Re: A few engine issues...



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.
