2018 Mule 4010 DFI light coming on occasionally
 

After about 20 or 30 minutes of riding the DFI light will sometimes come on. When it does, it either stays on for a minute or less before turning off, and I can continue riding for a while before it sometimes comes on again. Other times it will stay on and start to limp. After a rest, it will start right up and run just fine for another 30 minutes tops before I see the light come on again.


Most of my research is pointing to issues with the throttle body, but usually that is accompanied by a poor idle and/or stuttering when accelerating at a lower rpm. This machine idles great, always starts up strong and accelerates smooth. Wondering if the cause of my issue could be something different. Is there anything else I can try to remedy this issue before addressing the throttle body?


The mule has 880 hours on it and hasn't had a bath in a while, so it's a bit dirty underneath. Hesitant to do any washing and potentially cause another issue.

Just wanted to report that since I created this thread, the light has not come on (riding for about an hour every day since). The only thing I did was add about half a can of seafoam in with a fresh tank of gas since I was almost empty (maybe the cause of the issue?) and it's been running great.
