I need the code you read. Our shop in Vallejo is pretty close to you and services Infinitis...
You may have a problem with ignition coil resistance. In any case you should take it to a qualified professional for diagnostic testing and repair. If you start guessing what to repair, it could end up very costly.
what is the code number like po401
