I have 8 injectors that I have changed around from one to another but the values stay the same on each cylinder

1. 2.99
2. 2.99
3. - 3.99
4. - 3.99

I can put 1 and 2 in 3 and 4 but they stay just as i mentioned above.

I don't think 8 injectors can be faulty........

If anyone can help or think they know what the problem is please help. I've been struggling for way to long.

A4 as in VW A code chassis (golf/jetta/beetle), #4 (~99-06 roughly + Audi TT and I suppose A3). You said you were dealing with a B7, correct?

Depending on the age of the vehicle in question, you may very well need to replace the fuel lines. Beyond that, I have no idea.

Those values are just an adjustment of injection to keep idle.

ECU reads rpm after firing each cylinder, if the rpm drop, next fire on that cylinder will be with higher IQ.

If you moved around the injectores and the values are the same, it's not injector related.

If the timing is right, do a compression test. Low compression cylinders usually gives you higher IQ on those cylinders to compensate the weak power generated on that cylinder.
