On the LT-1, can someone confirm if the left bank is the driverside? Also, I think my left bank rich problem at idle is due to a sticking injector, does anyone know a good way to clean these injectors, ie take them out and soak them in something?

FYI - they are 30# svo injectors (redtop)

 

Bank 1 = left bank (drivers side)

 

Anyone have a good way to check if it is a sticking inj or just a pesky leak in the exhaust? I'm getting really annoyed that she is so rich at idle on the left bank when the CC305 cam is not radical by any means.

 

I know you can test for a leaky injector by pulling the fuel rail and putting the key to koeo and see if any fuel leaks. Exhaust leaks are hard to pin down, you could try checking all of your exhaust manifold bolts to see if they are still properly tightened.
