I have a metallic rattle when my revs drop (i.e when changing gear or after revving lightly while stationary).
I have an incline it may be something to do with my exhaust, but have not found any loose items in there! Another suspect is the catalytic converter, could this cause it?
It tends to happen when revved around 3000rpm, my engine the early 1.6 8v X16SZR, recent cambelt change and service etc. No problems after the cambelt change until now, so around 1500 miles trouble free since (Thats a year ).
Any other ideas or help is appreciated
