Thanks for the advice, never heard of ultrasonic injection cleaning, but defo look into it as I am having some issues, my check engine comes on now and again, when it does its only firing on 3 cylinders.I replaced plugs and think I will do the ht leads next, not sure which ones to buy thou. Should I stick with subaru or are after market ones suitable, I was looking at a set of bosch ht leads
As for my servicing I have replaced discs and pads, plugs and new full exhaust which cost a lot :o , changed to 5w 30 oil which I think the car runs better with, was thinking of replacing maybe the transmission fluid, fuel filter,air filter, pcv valve, not sure if I need to do transmission fluid thou? anything I have missed?
