I have bought a code reader.
The following codes where present -
P0302 - Cylinder 2 misfire detected
P0130 - O2 Sensor Circuit Malfunction Bank 1 Sensor 1
P0352 - Ignition Coil B Primary/Secondary Circuit Malfunction
I read that if a coil pack was faulty, this could cause an overfuelling problem, which in turn would bring up a O2 sensor fault.
I bought replacement coil packs and leads, cleared the codes and fitted the coil packs etc hoping that it would be an easy fix.
However, this is not the case...
The car starts fine, no issues, then a few seconds later, once it begins to idle, it becomes very lumpy and the RPM goes up and down like a yo-yo. I haven't driven it, it's just been started it on the driveway.
I can also smell the unburnt petrol in the exhaust fumes.
The problem I have now, there are no fault codes coming up and the EML is off.
