Alright, When I fire my truck up after it has not ran for several hours (overnight or during school) the idle sounds terrible like the turbo is not spinning. I have been letting it warm up for 5 or more minutes. When I go to drive, it has no power at all, tops at about 20mph, smokes extremely thick black smoke, builds 0psi boost even at WOT. and sounds terrible (again like turbo is not spinning). I drive like this for about a mile, turn off the truck and then fire it right back up. After that it runs like new, everything normal. It only does this after sitting for more than 3-4 hours. I have all of the mods in my signature. I unplugged the EBP sensor to see if that would change it and it made no difference. Any suggestions of help would be greatly apprieciated. Thanks in advance.
