Hello everyone.

I have an error code called p300 and p304

I have switched spark plugs, spark plugs and coil, and it did not help. But now I have switched on injection valves 1 and 4 .. and now the error code is p300 and p301. the valve costs 400 $. So I want to hear your opinions, if I just have to change the injection valve?

It is a Fiat grande punto 1.2 8v gasoline.

Hope to answer

Hey, yes, what you are saying makes sense.
DO NOT get the new injector from Fiat... not at that price!!!!!!!!!
Get the product code of the old one, then search ebay.. should be able to get one under 50 euro.
