Hello friends,

I have the same problem with a jumper 2008.
We have installed 4 new injectors, no improvement.
Now we have renewed the ECU for € 1000, no improvement.
Always the same problem, P1304 injector learn fault, correction values too high.

Does anyone have a solution to this problem?

Many thanks in advance
