So, recently, I did Engine oil change, coolant flush, air filter change, clutch oil flush, and also opened up the stator box to fix oil leak. Everything went well. But now a few ins after the cold start, the engine is revving high when I press the clutch lever and in gear. Also, after driving for 15 mins, I get error code 14. I'm not sure if I messed up the wiring when I had to remove the stator cover or is it a genuine coolant sensor issue. Also, can the revving and error code 14 be relevant or separate problems? Did anyone face this issue before? I feel like my mpg dropped too.
