So I just got my FRS back from Toyota, the car was having a hesitation issue at 4000rpm and sputtery misfirey cold starts that'd seem to level out after reaching closed loop. they replaced the high pressure fuel pump which seems to have solved half of my issue. Now I'm getting 2 air fuel imbalance codes.
The sputtering cold starts sounds exactly like this: https://youtube.com/shorts/8vZuumwxIKw?feature=share Any suggestions are greatly appreciated and if you have experience with this issue your input could go a very long way. |

Try to do some data logging. Google those codes. The forum "search" doesn't seem to work too well. My 2013 had these code after a rebuild and my tuner finally just turned the codes off. I never found a definitive answer to the codes but my car is running great.
