It happens again today, I did some datalog and the A/F & fuel trim data was normal. But I found an other trouble code P0139 (O2 sensor circuit slow response) without an engine check light on dash board. After clearing the code on Hondata App everything got back to normal. BTW I got RV6 catted...
Yes I got the same problem with my FL5 yesterday after driving at highway but without engine check light (I blocked the DTC0420 code), then I reflash the hondata to got the pops back. If you could find where the problem is pls let me know, Thankyou!
