[Non Corsa] Ignition coil fault code on astra

[CorsaEdi]

Eml is on the astra (mk4 1.6 51plate) so I read the code and it said ignition coil so I changed coil pack and cleared the code but it came straight back on and car is mis firing, any ideas?

Check the plugs & connections to the coilpack. Make sure nothing is preventing the coilpack from seating properly.

What code is it showing?

Think the code was p0354 but don't hold me to that

Might be worth checking the cam sensor, if that plays up the sparks will be stymied.

Also check and clean and WD40 all the ECU connections.

Thanks Taurus, also any way you could show me a picture of where and what the ecu looks like on these engines? Thanks

As you look into the engine bay it's on the right hand end of the engine.

Have a look at this link - it ought to show a photo with it labelled - 1.6v 16v Whats in your engine bay? | Vauxhall Owners Network Forum & Club - Insignia | Antara | Mokka | Adam | Ampera | Vectra | Astra | Corsa | Signum | Zafira | Meriva | Tigra | Agila | Vivaro | VXR

Just read that but I am struggling to find the parts it mentions so where could I take the car to have it sorted? Or anyone on here able to dumb it down for me lol

Looks like one of the cylinders has either worn valve stem oil seals or a stuck / damaged oil control ring on the piston ring. Pretty common on these engines to have the misfire from the plug getting gunked up with oil.

Would a compression test show that?

Also if it was that mate why would it throw up a ignition Code?

[Hardcore]

From what i read the ignition fault shows up because there's a misfire, but the misfire is caused by the plug getting stuck up with oil.
I could be wrong but there was a discussion on some other forums where that was said to be a common issue
