Today, while driving behind me, my girlfriend noticed that each time i shifted a puff of smoke came out of my car. I was thinking now could this be? turbo related? And wondering how, if at all, the clutch was related? Could i need new rings? I have a 25g turbo btw.....It has smoked before but only after i stall then start it up again. Its due to the 2ndary fule pump......so if anyone has any ideas what i could be hit me back pleez.....
