Car Hesitation help/advice needed pls - 2007 G35
Hey guys. This might be long but I need help. Here's my story.
I have a 2007 G35 Sedan with a lot of miles. 160k miles. I have not had any issues with the car and absolutely 0 check engines/ codes. For some time now my car been hesitating at take off and during bumper to bumper traffic. It feels like the RPMs would drop and then go up. One day my RPMs dropped enough that my car turned off in traffic.
I took it to a mechanic the next day and he saw a Bulletin for 2007-08 G35 sedan needing a ECM/ECU reprogram ( ITB11-018) . He suggested I go to the dealer and get that along with a relearn.
I go to the dealer and they won't do it. According to them and their computer (I still have no check engine or errors), my exhaust timing sprocket and VTC cover failed which caused a misfire and why I'm feeling hesitation. They said the reprogram will do absolutely nothing.
I end up getting 2,3,4 other opinions from mechanics and none agree with the sprocket issue that the dealer mentioned. According to the other mechanics and when they hook it up to their computer, They see no errors showing up or any misfires. They all mentioned if my sprocket was bad and causing misfire i would be throwing codes left and right. They also recommend I get the ECM/ECU reprogram. I tried going back to the dealer but they still wouldn't do it.
Have any of you guys had this problem? Any suggestions?
btw on the description of service, the only code they have next to the suggested repair is J0001.
