Man, do I feel stupid.
I accidently had hit the HOLD button on my Sears Duty Cycle meter and that's why it was displaying 81.36% in KOEOff mode. Also, output signal type must be set to %. Now it reads 50% in KOEOff mode (perfect).

When Arthur had me clear the memory to reset Code 17 in socket 3, it must have reset my duty cycle as well since after I corrected the buttons on the meter, my duty cycle was about 80% (way to lean). Turned the set screw CW and now it runs between 45-50% on idle (perfect). Only problem is that at 2000 rpm, duty cycle is 65-71%. Spec calls for it not to vary by more than 10%. Is this cause for concern, and how to correct?

Issue # 2: (Original problem)
I also just replaced my front speed sensor and my rear crank sensor. Still getting the code 3 TN/TD signal (RPM) interrupted on socket 14. It comes back immediately even after clearing the code and clearing the memory of the module. Any ideas on how to correct this code?
