The throttle position sensor has the car getting really poor gas mileage, showing plums of black smoke at intervals and losing power! This is typical of a Nissan with their cheap parts seemingly designed to last just out of warranty. I've been trying to get this car running at maximum for nearly a year now but this one glitch has been a pain in the rear not to mention pocket. There was NO specific code for this problem noted unless you have a $30,000.00 Nissan specific reader. They do not want you to be able to get a proper diagnosis else where so they can burn you a new one. Nissan has to make their cars look good so that you will buy based upon that.
