losing turbo when hot, mech can't duplicate
04' 6.0, EGR delete, cleaned out cat, recently cleaned turbo. my truck has been doing this now for going on 2 months. whenever the truck has been driving for about 1 1/2 hours I will suddenly lose my turbo but all my gauges read fine, I've got plenty of oil pressure and my truck's running mid range on the temp gauge. I'll be going along about 60mph and put the pedal down on a hill or to make a pass and the truck shifts then takes for ever to accelerate but if I can hit about 75 it will come back but die off again as I slow down, and be completely gone everywhere else. I pulled and cleaned my turbo about 2 weeks ago thinking it was so dirty it was sticking but it hasn't helped, I knocked out the guts inside my cat thinking it would fix it but it didn't change anything, I've also changed my MAP sensor but I'm still getting MAP codes. every time i take it to the shop, it sits for a couple days till they look at it (like from sat to mon) and then the problem disappears magically, they drive it and no problems whatsoever. anybody else out there able to help me?????? I'm going insane trying to figure this thing out
