Hello everyone.

I really need help ..

I have a Fiat Grande Punto 1.2, 8v with start and stop.

It started with start and stop not working anymore, and then the engine light started blinking at the same time as the orange triangle.

When I check the error code, it tells me the following: p300 and p304(misfire cyl 4). When I delete the errors, then start and stop work again for a couple of hours,

I've checked the compression and it's ok, I've switched the ignition coil, ignition cables and spark plugs.

What happens is that the car shakes when I'm idle. and if, for example, I'm on my way up a hill, it's very difficult ... and it's especially when it's cold.

There are also some click sounds, from the engine compartment sometime in between, but only when I drive.

I hope; that some can help.

thanks in advance!

Hey all. I have switched injector 1 and 4. And the new misfire code is P301. Think i will change the injector.
