My car has been doing something funny, sometimes it idles funny and when I gas it hard it tends to jerk and the power isnt there. I am thinking it is a fuel injector. Well the code 0603 came up and its cylinder 6, which one is that? I checked the haynes manual and it didnt say.

 

Cylinder 6 is the in the front bank (closest to the radiator), the right-most cylinder (towards the driver side).

You might have a bad coilback or fuel injector for that cylinder.
