have a problem with the CEL coming on ocasionally in the winter (cool damp days and the light flashes) when the revs get over 4500. Then today the light came on and stayed on, has anyone got any ideas what it could be?

I will be plugging it in later today through the obd port

 

could be a fuelling issue as on cool damp days the intake temps drop, only a guess but the codes will shed more on the topic, good luck

 

Sounds like a misfire of some sort. Could be fuelling, plugs, coil packs or even NPS.

 

just noticed your from sheffield, take it to sheffield subaru service m8, tell them addi sent you, they are a top bunch and will help where they can, no need to book it in just turn up and give martin a shake lol,

came up as misfiring on cylinders 1 & 2, yet its running fine. Now I'm confused

 

Neutral possition sensor? What year is car? Bugeye prone for it
