06 tC running rich
I have a 06 tC with a check engine light that reads runnig rich bank 1 i have changed bank 1 and bank 2 senors as well as the MAF but still get running rich engine light I do have a AEM cold air on my car. Does anyone have any other things it could be? Also I was told by a O'riley's worker that it could be a problem in the fuel rail or injectors is there anyway to check the injectors or fuel rail with out taking them apart?

I wouldn't think its the fuel rail, it sandwiches the injectors and acts as a manifold for fuel. Maybe it clogged, and if it clogged you sure as hell would not be running rich.
Was the light on before you installed the intake?

it wouldn't be my first guess. you could pull the ecu fuse or disconnect the battery for several minutes and then see if it resets and fixes it, but that won't guarantee you won't have the issue come back.
as you said, there wasn't a problem before the intake. so the best guess would be that the intake is the problem, resetting the ecu will only hide the issue for a short time.
there were early intakes for the tC that weren't sized properly and cause problems like this.

mine did this for a few months now, ha my intake for 5+ yrs too. but that means your MAF sensor is going out. had the same code as you, eventually with time your car will start going in "limp mode" and get annoying.
look into a new MAF sensor (stay with denso) but for now leave ur battery unplugged for 15 mins. then let the car learn its ecu again.

well ive done two differet MAF sensors. one failed on me snd didnt even take the code off (noticed the battery was still hooked) so when i installed my last one i left the battery unplugged and installed it and no more CEL

Did you get the correct intake? The 07+ intake will not work correctly on the 05-06 models. I believe people are still able to bolt them up but the MAF fitment will not be correct and will cause issues. I have not compared the two side by side to see if it would still bolt up but I believe it will, and I know for sure it will not have proper readings if it does bolt up.

There is only one bank on an inline motor, so you should have bank 1 sensor 1 and bank 1 sensor 2 for the O2 codes.
Beyond the model intake I mentioned in my last post, has any actual troubleshooting been done? For example, actually reading primary 02 voltage levels while running to see what the actual reading is? Pulling a vacuum line while watching O2readings to see if it makes it go lean on the reading to see if the O2 sensor is responding properly, etc?
I tend to stay away from the typical parts swapping technique of repair, since it almost always costs way more money and many times still never fixes anything. I do realize that some dont have the tools to perform some of the tests, but in that case a good private mechanic ( not the dealer who can very likely take the parts swapper approach) would have been cheaper than he parts you are throwing at it.
Also, be cery certain you are not touching the sensor element in the MAF with anything, even while cleaning it.
And if you are running an oiled filter be very sure you didnt over oil it, which will foul the MAF. If it is a short ram, dont run an oiled filter.
