Has anyone had to replace their injectors on the z20let?
If so at what mileage and what symptoms were you having to make you want to replace them?
I'm getting a fault code reading P0204 Injector Circuit Malfunction - Cylinder 4.
I'm guessing this means the injectors are screwed- I do run the fuel down right to the bottom red line now and again so that prob hasnt helped. Always use 97ron fuel though and redex additive once every couple of months.
Is there anyway to clean the injectors apart from using the redex/similar stuff? How easy are they to remove? And how much for new ones?
Would be very grateful for answers to any of the above!
