Noticed the idle AFRs were getting really lean (and staying that way) as I was coming home from work. I get home and check things out and sure enough, one of the studs at the turbo flange has sheared completely off. Time to completely take apart everything once again and replace that stud. To make matters worse the stud is an adaptor - it has two thread types! Where the hell am I supposed to find a new one and now I'm worried it won't be strong enough. WTF?!
