Slight differences in engine performance, injector performance, AF sensor performance, etc. Nothing to worry about.

good luck

Ok thank. I am just trying figure out why spark plug 1, 2 &3 have more carbon burn or darker than plug 4-5. As you can see from the picture bank1 air/fuel ratio is slightly rich than Bank2. Are the plugs 1-3 (rear of the engine) from Bank1?

Trim is adjusted to achieve desired ( 14.7:1) air/fuel on all cylinders. Some cylinders will inevitably be slightly richer or leaner than target. Bank 1 is rear cylinder head w/ 1-2-3 cylinders.


good luck
