[DML] Re: Injectors

["Harold McElraft" <hmcelraft@xxxxxxx>]

The difference in injectors is usually the pressure at which they open 
and how much they open at different pressures. Therefore, it is a good 
idea to use the correct ones. Five different numbers can look the same 
on the outside but all perform very differently.

I am not a big fan of cleaning injectors - I personally do not believe 
it is worth while. If more than one injector is leaking, either they 
were not cleaned properly or I would be suspect that the fuel system 
has had some moisture in it. That could mean some of the other seating 
surfaces may be scored too. If one is leaking I would suggest 
replacing them all - with the correct ones - and doing another 
pressure test.

BTW, a leaking injector usually means a rough running engine 
especially at cruse and idle. Any symptoms?
