Literally could be anything. You need to get it looked at by someone competent before throwing parts at it and guessing.

Yes it going for a scan on Saturday so helpfully it will show the fault code ??

With an EML, even a £16 cheap OBD2 reader will tell you the issue. Buy one from Amazon, Euro Car Parts etc. They're usually good enough to even tell you the cylinder not firing properly, should it be plug, coil or fuel related.
