hi mate ... i have the same issue but a misfire on cylinder 1 ... i have replaced the plugs .. replaced the coil pack on cylinder 1 and also the nps switch as this also fires up a misfire so a few posts on here have stated .. i've just added some injector cleaner into the fuel ...also reset my ecu ...my car by the way is a my04 wrx sti type uk ... just waiting on the fuel to go low then going to re-top up and see what happens .. if that dont solve it then its off to dealership for a proper shakedown to see if they can solve it ..

Ok quartz i might try the injector cleaner too. How did you reset the ecu? I have a subaru cat 1 alarm and immobiliser on it and dont want to run the risk of not being able to start it again after disconnecting the battery....If you know what i mean

reset via my laptop .. software romraider ..hardware the vag-com odb2 cable .. .. mines a newage didnt try the battery trick .. as its known not to work .. and didnt fancy leaving my car with no alarm all through the night lol ... ..

hope you have some luck .. because it comes damn expensive replacing a few things ..

Yeah understand about the expensive bit, just like children.....LOL and i have two of them.
Budget is king..LOL
I dont mind spending the cash when i know it makes a difference.

Keep in touch i am very interested to see the outcome on both instances, being the fuel and the diagnostics check

Just an update on the sensor. A big thankyou to pinky. I had the precat out and the sensor was completly snaped off by the ball of metal which was the cat!!!!!

So the preat pipe has been gutted and new sensor fitted

Also now have a vf30 and sti intercooler and a decat downpipe. Looking for some pinks and a map
