Hey I have a 00 blown gt and I am throwing a check engine light code that says bank 2 rich. Car runs great but has a rough idle. Any ideas? Injector or coil pack?

i would guess you have a leaky injector.

A code P0175 may mean that one or more of the following has happened:

The MAF (Mass Air Flow) Sensor is dirty or faulty. Note: The use of "oiled" air filters (K&N, etc.) can cause the MAF to become dirty if the filter is over-oiled
There could be a vacuum leak.
There could be a fuel pressure or delivery problem

i would presume this code to come on while boosting. are you running a FMU or how are you adding additional fuel while under boost.

a leaky injector could as well be the cause. usually when these go bad, you would feel the misfire as well.

Clean the MAF first, then pull the front o2 sensor from the drivers side and clean it with a wire brush.

I had the car tuned yesterday and the tuner said that he cant change the fuel from bank to bank. There is no air leaks anywhere because I have a vac/boost guage. Can a fuel injector get leaky? How can I check injectors or coil packs?
Thanks
