I have an 88 Alltrac with a st215 motor. Runs, starts and drives, but is running pig rich. I can share the emission numbers if wanted.
Torque Pro recording of readings
So, I made a short video of what my ecu is showing while idling. No audio, but figure the gauges tell the story. I did idle and 2500 rpm hold.
I have replaced o2 sensor and plugs. Not sure where to look next. The fact it shows a high load makes me wonder if that is tied to the issue.
Thanks for any feed back.
