I bought a used Yager GT200i online. It runs like crap, especially until it warms up. It gives three separate engine codes.
#3 P1120 TPI adaption fault
#23 P0136 O2 sensor circuit malfunction
#25 P0171 Close loop fault
Can anyone give some advice? Could they all be related to the same problem, or bad part? Where can I even get parts for this scooter? I can only find some cosmetic parts on Ebay. Thank you very much!
