my 7 is constantly idling and vroom, vroom, vroom, vroom plus its burning gas(black smoke). sounds bad to me could someone help please? and at the attached thumbnails that thing thats bothering me also is the thing right there. is it leaking also? if it is how do i get i fix?

 

Looks like oil is spitting out there. You will probably wanna replace the o-ring that gos between the throttle body and elbow and that should solve that problem at least.

 

any idea where i can go buy it at?

 

local mazda dealership, pretty cheap.
