Looking for some help with my stilo 03 plate 1.6 16 v, it has started running very poorly and is misfiring on cylinder 1, I checked for codes and got p0300 and p0301, with engine running I unplugged coils 1 by 1 to confirm misfire is on cylinder 1, I then swapped over the coil from cylinder 1 to 2 and misfire was still at 1 so it's not the coil, I then did the same with the spark plug and it's not that either, the spark plug from number 1 was wet with fuel when I removed it so fuel is going in, I checked the resistance of all 4 injectors at the injector multiplug and they are also all giving the same reading, so where do I go from here? Appreciate some help from someone with experience with stilos, thanks.

You might still have an injector related misfire, so swap injectors 1 & 2. After that it will be a compression test.

Thanks for reply, the injectors seem impossible to access, any advice on the best method of removal? Thanks

Have a look at this fuel injector rail here on eBay

Once the rail is unbolted and disconnected from the head and its supply / return pipework, the injectors can be removed from the manifold still connected to the rail. The injectors themselves are held onto the rail by a clip.

Sorry, my post above relates to 1.2 engine which I thought yours was. I don't know if the same setup is used on your engine

Ha ok thanks for the info anyway I'm going to strip it today
