One of my 8 injectors works not always on lower rpm (only on lower, on higher rpm everything is o.k.). I would like to test them, to find whis may be faulty.

Is there any solution to test the injectors to see, if they are in googd condition or not? The engine is disassembled now.
Its fine to open up an old thread especially if the original question posted is similar to your problem. If the two problems are different, go ahead and start a new thread.

Give us some more information about your truck and what exactly is happening and we can go from there.

o.k., thanks!

So my truck is an '74 F250, and I have a new engine in it from an '99 econoline E350.
Sometimes on lower rpm a knocking noise is comeing from one cylinder, but on higher rpm is everything all right, and working fine, you can not hear this knocking noise. It happens often but NOT every time.
I think that one of the injectors should be faulty, so I would like to check them.
Thank You for the help.

And you said the engine is disassembled?

I would pull the injectors and send them to a place like Rosewood and have him bench them.
