Hey Guys,
I have an 05 f-350 srw 6.0 6 speed with 41000 miles. I towed my first heavy trailer the other day and when in a hard pull mostly third gear and between 1000 and 2000 rpm my trucks starts jerking like it is missing but you can hear a coughing sound coming from probably the turbo. Also when i shut my truck off you can hear a grinding sound as the turbo winds down.The truck builds boost but is sluggish doing it and has little low end power pulling out.Any info or suggestions would be great. Thanks
