the mechanic told me he took it apart and did a test, he told me injector number 6 isnt working at all, and number 5 is on its way out.
but he recommended i change all of them or he said they will rebuild them.
but im not sure if i should rebuild all of them, or just the 2.

but i know i can buy them new for the same cost as the rebuild.

any recommendations?
thanks
