So I installed MSPNP2, that I bought from DIYauto. Been having a hard time get the car idle right, ever since I installed MS. So today with the car running I pulled the connectors on injectors 3 and 4 and it made no difference. With 1 and 2, the AFR shot up to 20 something, so I know both of those are working. It will run fine with the stock ecu so I doubt any of the wiring is messed up. And I also have the same problem when I swapped over to my stock injectors, I doubt it is an injector problem.
A bad MS? Is that a thing?
Anyway, any clue on what I check next?


Here is my tune with a log if it help
Thanks in advance
