I was driving car around Saturday night got on it few times, motor was making a noise like something lose. Went out next day cranked it up, well tried. It was hard to start, wouldn't idle. My o2 meter was all the way lean, running like crap. Found out the bolt that goes into side of turbo thru bracket that bolts to intake fell out and it was sucking air. You wouldn't think that hole would go all the way thru. Well new bolt wouldn't tighten up so I put thread lock on it.
