i have a 17 l5p and took off the intercooler pipe for the turbo on the driver side to replace some parts and i everything back together as soon as i got on the highway the bottom connection fell of the intercooler and ran for a couple minutes after realizing it had disconnect, after that the truck didn’t accelerate and turned off, i secured the pipe and turned the truck on but only runs for a couple seconds and powers down, the turbo starts making unusual noises and it blows off air thru out the air filter suggestions what the problem is?
