This, is bad.
Here we have charts showing the power output and air/fuel reading of each cylinder. Runs 1-9 are the front cylinder, and 10-20 are the rear. The bottom half of each chart shows the air/fuel mixture across the RPM range at each throttle position which are not labeled here but are 5, 10, 15, 20, 30, 40, 60, 80, and 100% throttle respectively.
The dashed line going straight across is set at 13.2 - the target fuel ratio that the fuel injection system has been programmed to run at. As you can see, it is way off of its target.
