Hi every 1 i got a 52 plate bugeye (non-turbo), my engine management light has once again appeared, ive had a computer readout it says shes missfired on cylinder 4, ive had my plugs n leads renewed, but to no avail, anyone got any ideas wat it means or wat she needs to repair this fault.
Thanks in anticipation,

I have a52 plate WRX that has a misfire on 1-3 & 4. The guy at the Subaru dealer told me a few things to try. I have already replaced my Coilpacks and plugs from when it first came on and the code said the same problem missfire on 1-3 & 4. Dealer said it's unlikely to be a faulty sensor as there would be an identifying code for them.
