My 2007 mustang convertible shakes when radiator fan kicks on and It's in drive at a idle,it also vibrates when I use my power windows and when my top is 1/4 inch from being all the way up. I need ideas please
I've had it all checked at a auto part store they say battery and alternator is putting out what it's suppose to my lights don't dim if I have them on and wipers etc. I've even had it checked with a computer code reader and it has no codes that show up.
I think it may be the dreaded 4.0 850ish rpm exhaust vibration. you've described the symptoms perfectly. I understand weights on the down pipe before the Y was the factory service bulletin to solve this problem. I have the vibrations too and they are worse with an H pipe and duals. I am going to try soon with weights myself. I've read about this on a number of forums, anybody here hip to some plan or another?
