code 45 on a non-california model? please help!

[mss5413]

Has anybody ever retrieved a code 45 injector leak on a non-california model? My ECM and chassis is a non-california model type, but yet it still shows a code 45. I have a bad exhaust smell and rough idle sometimes as if the fuel mixture is incorrect, but do not know why it is doing this?

All spark plugs are dry, and 45 is the only code stored.

The weird part is the check engine light is not on while driving the car.Nissan did not say anything else to me about the code in the past other than the fact that I had a fuel injector leak when they diagnosed the vehicle, which makes me wonder. I know I have a problem, just can't figure it out.

I replaced the injectors and still have the problem.

Any suggestions would be greatly appreciated.

are the injector o rings new and lubricated etc. you could have a bad ecu. or anything that causes a rich condition that ecu cant correct. ie temp sensor

actually, I pulled the injectors recently to make sure that I lubricated them properly and put them back in, same problem.

I did consider a bad ecu, but there should also be a dtc for that, or I could be wrong. I just wouldn't want to spend the money on a new one, and it not solve the problem. I could try a new coolant temp sensor since they are inexpensive anyway, and I replaced it about 3 years ago.

Thanks for the input, since this is the only reply thus far. If you come up with more suggestions, please keep me posted.
