I think I have some weak injectors or something on the right bank. I had some dyno tuning done this weekend to try and lean it out. But once the car goes closed loop the right bank goes to 108-118 and will not move until I start driving again. The left side at idle is 160. I just replaced all the plugs and installed a new o2 on the right. I am thinking that a few injectors are weak on the right side and spraying too much fuel. We bumped the fuel pressure up the other day before the dyno tune and after that is when it started running so rich. Any thoughts on the injectors???

more likely its caused by your TB and cam than the injectors. what brand TB do you have? some have more problems than others with what you are describing.

 

I have a bbk 52mm tb. I wasnt doing this before i bumped the fuel pressure up the first time I was on the dyno. Thats why I was thinking the injectors were too weak for the fuel pressure. They are stock and running on 44-46 psi. I am going to swap them tomorrow and clean the tb and see if that helps.
