Have you replaced your injectors?

I still (well have always had) a slightly rough idle. If I run a bottle of injector cleaner through the tank it almost disappears. Injectors are original as far as I know.

Mounts (all three) have been replaced) along with EHA etc. Valve job 65k ago.

I think I will replace the injectors and see what happens.
