P0300 Misfire

[JakeyCUK]

Hi all, been having a nightmare of a time recently with the Clio. With help off this forum I've replaced my AC compressor as the last one bit the dust after an incident with some standing water. Anyway, just before I fitted it, the car started missing and engine management light flashing. Got a fault code reader on that returned P0300. I stripped it down, took the plugs out and got good reading off all 4 leads. Plugs were a little dirty looking but nothing major, plus they've only done 12k (official NGK R's). Is there anyway I can positively identify where the fault may lie before I order new plugs, new leads and a new coil pack? Standard on-board diagnostics returned no issues with injectors, only a h--- stored fault. Not sure if this has anything to do with it though?

Thanks folks

Ok well good news! My Dad did some testing today and looks like injector #2 has died. Good news because I can actually get it back on the road soon! I found some old posts from 2013 & 2013 and people were quoting the injector as £75 a piece but I've found loads for around £30 off eBay. Is this right or does that seem too cheap?

Thanks

Thats the right one and is a "genuine genuine" one.

Do I need to order a full set of seals for replacing a single injector as I will be removing the fuel rail from each one?
