Guys,
About what mileage should the injectors be serviced or replaced at. I've got 145k on and I'm certain mine have never been touched, at least since last 45k. Does that injector cleaner additive you can buy anywhere work? I think Wynn's puts it out along with other brands.
Regards,
Gary.

Hey Gary

The in-tank cleaners... well, they halp a little in my opinion... but not a lot. The purists would say it's a total waste of money.

They'd probably benefit from a clean, but probably not completely necessary unless you're having dramas (bugger to start, foor fuel consumption, pinging etc)

Repco will do a changeover for sonically cleaned ones, but its a bit expensive.

You can also get a carbon cleaner that you plug into the fuel rail and clean them like that... but nothing beats a proper dismantle, clean and flow test.

Ok, thanks for that. I've got no huge problems, only an occasional miss on start up. Disappears once I put the power on though. I'm going to be driving some serious km's in the next few months and thought I might have it all tuned, and serviced ready for the trip.
Regards,
Gary.
