CT130

Hello everyone, I have the above code for a while now on my 2k infiniti I30. unfortunately, I am due for emissions so i would like to get it fix. The code does not identify the failed/ing coil. I am guessing I have to replace them all. No signs of misfire either. Only CEL. I need to get rid of the CEL!!
Where to buy OEM/Compatible coilpack for reasonable price? (Include part#)
Any recommended mechanic in the New haven area?
Thank you.
