Car randomly starts smoking and stops

[Eddie moore]

Hey guys, I recently picked up a 2010 Mazda speed 3 about a month ago. The car is equipped with gtx3071r a 94 octane turn front mount in cooler and a bunch of goodies like that. I’ve noticed every so often I do a pull and it smokes out the highway grey smoke and smells like somethings burning for about 10-20 seconds, then stops smoking completely even if I do another pull. This happened to me twice yesterday. It’s seemed to have gotten worse. The car dosent over heat and still drives fine just wondering what you guys might think it is. Is it safe to keep driving it in negative boost just to get around? Cheers

probably running rich but could be a bad PCV, check oil levels, did it come with an access port, if so take a WOT log and post it. also check spark plugs and gap should be 0.026"-.028"

any noise from engine? stock engine I presume?
