so I went and tried an injector balance test to see the state of my injectors after a couple codes popped up and went away. got some strange results and i'm sure I'm doing something wrong. I see that numbers should be + or - between 0 and 10.

balrcyl1 - 217 mm3
balrcly2- -1919 mm3
balrcyl3 - 1347 mm3
balrcyl4 - 2046 mm3
balrcyl5 - 1312 mm3
balrcyl6 - 817 mm3

this was at 1800 rpm at 47 mph

I have no idea whats up with these readings
