Sup guys been a very long time since ive been on asking for help and what not. But this is frustrating me. I just got a error code 43 from my ecu and i got it a few weeks ago but i thought i fixed it i changed my o2 sensor ( it was dead) and flashed my ecu and all was good no codes. Then today some dude was riding my ass on the freeway so i speed way up and boom engine light. so i checked the ecu and code 43 now any ideas on how to fix what ever it may be now i know its not the 02 sensor so what else may it be. Bad injectors maybe i just dont know help guys thnkx

I had same problem.
Took the oxygen sensor back and replaced it. No more codes. All was fine for couple weeks till I rung it up wfo one day.
New sensor been in there 4 months now and okay. The first one must have gone defective.
