my '88 5ktq wont idle hardly at all. It will idle for 20-30 sec. or so at a low 600-400 before it quits. I have noticed that it will make close to full boost 1.2, occasionally 1.3 when driving. So I don't believe that I have any cracked turbo hoses. Any one got any quick checks? Just been too damn cold to really check it out. Regards Britt Crowell
