leaky injector? Why one bank rich?

[IXRperformance]

I have a blown 00 gt. What would make one bank richer than the other? Leaky injector?

maybe a injector sticking a little.. but most likely it's the tune or a bad 02 sensor.. most likey the tune

but the tuner said that there is nothing he can do because there is no way to adjust fuel from bank to bank only the over all fuel curve. I am throwing code 0175 bank 2 rich. What causes this?

how do I test for a leaky injector?

 

[Mike97gt]

at the dealer we can use our WDS scan tool and run a injector flow test.. that would show it..

if a injector was leaking that cyl would most likly misfire.. a leaky injector would flood that cyl out..

mass air sensor.... maybe some oil on the sensor element might wanna check that out first
