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.
