Well I took my Z into the dealership to have a few TSB's done to it, I have a rattle in the trans when sitting in neutral, I also have the grease streaks, the cruise control didn't work. The main reason I brought it in was because I was have acceleration problems at 3/4 throttle while driving on the highway, well before I brought it into the dealership, I changed my rims and put back on the stock ones. To my surprise I used the cruise control the whole way there and when I wasn't using that I was trying to generate the same problem with the throttle and acceleration issues. I couldn't manipulate the car to do that either. What gives. Is it possible that the car uses the tire pressure sensors for more than just that, does the car use it as well for throttle control and cruise control? If anyone has any knowledge if they are linked or not I would really like to know. Thanks.
