Premium. Now that's cold I keep the windows up most of the time. About a week ago, I noticed that under moderate acceleration and >3000 RPM or so I can here a noise / vibration.
1) Seems to be coming from aft of the shifter
2) Not dependent on gear - most noticeable in lower gears but I can hear it up through third ... probably does it in all but as vehicle speed increases, so does ambient noise
3) I have a Barton shifter / bracket installed, this is not the same NVH that the shifter introduced
, and seems to be coming from aft of where you typically hear the NVH from the shifter
4) Doesn't do it every time but about 80% of the time
The car is running great - not issues thus far, about 10k miles. I also have Boss 302 sides installed. I went under the car and verified that the shifter bracket and exhaust pipes were tight, they seem so.
My car is very loud with Roush AB's and the Boss sides, so there is a lot of vibration normally. However, this is annoying.
Anyone have any idea of what could be in that area that could vibrate? I already removed all loose items in the glove box and center console to make sure it wasn't any junk rattling.
