I had a mechanic sort my turbo out a few weeks back, and he mentioned that it sounded like one of the injectors was going bad. I've suspected this myself for a while as things are pretty rattly. I haven't done a leak-off test or anything to confirm this, but I'm wondering if I can get in a pre-emptive strike and arm myself with a bit of information about injectors, before the proverbial hits the fan.
If an injector fails (Injector <n> above knock threshold), what happens? Limp mode? Total breakdown?
I have an F-Super - is it possible to recode the existing injectors? Is there any point?
If I need to replace, should I replace all four at once? Or just the bad one? I'm concerned about cost as I know the Delphi injectors are not cheap.
Finally, is it a job I can do by myself? I know my way around a bag full of spanners.
