The main thing I don't like about getting injectors serviced is I'd like to 'know' they're bad before sending them out. So I'd want to test them first. Somehow.

Plus, you don't even get 'your' fuel injectors back when you send them out.

When I recently replaced my spark plugs, all looked good.

Plus, I have 'lean conditions"; not misfire conditions, per se.


A few months back, we pulled the injectors from a v8 engine (BMW) from a friend of mine's car.
The shop that cleaned them, handed out a nice report with the condition of each injector pre and post. 3 or 4 of them (I cannot recall exactly) had less than 30% flow. All had the spray pattern out. The car had about 140 k miles (225 k Km). Those were his injectors before and after. They don't inter change them. If one is toast, they tell you so, and you will have to buy a new one. At least that's how they operate here, where I live.
If you have "lean" condition, and IF it's related to injectors, you need new O-rings.
