can anyone help me with a method to test my secondaries and see if they are working? s5 n/a

 

You would know if they weren't. When you hit 3800 rpms under load it'd feel like slamminging into a brick wall.

 

Swap your secondary fuel injectors with your primary ones.
Is the problem still there?

You can pull them and flow test them like it says in the FSM. Also put a negative and positive lead to each injector to make sure they click. Dont leave the wires on the terminals long. Just a split second is enough to check if they can fire.

If you already have them out and you can confirm they click then you might as well send them to get cleaned and blueprinted.

 

Disconnect the boost sensor hose and rev the engine above 3500.
