asked by on

I did diognostic on my car came back with a code p0204 injector circuit 4 should I replace just the one or all six injectors on my car?

My car has 110444 miles.
My car has an automatic transmission.

You should only have to replace just the one injector. I have seen injectors last over 20 years without an issue. If the injector is on the underside of the intake then you may want to replace the injectors as a set.
