Good afternoon, about 3 months ago i was suffering injector chatter and had a code pop up pointing to injector number 2. Having replaced number 2 the problem was solved but has now returned and occasionally throws up a P12A5 code, it is not clear but i believe that it is pointing to injector number 2 again? has anyone had any experience of this, I don't want to replace the other three injectors to find that is is number 2 that has failed again and i have wasted £800.
