Hi I have a 01 lb7 that has 225 km.original...stock. I know my injectors need replacing but with a variety of closed loop cleanings and fuel additives ive managed to get by with them. Not making oil...but do have injector knock at idle. Truck still made power and decent fuel mileage. Ive noticed after a filter swap that the system will not stay pumped hard for longer than a minute. within two or three minutes it is soft.This is shut off. The truck seems to be starving for fuel. no smoke at the pipe. runs decent without a load. Upon visual inspection I also noticed my turbo wheel has made slight contact with the iside of the housing. Maybe a pencil thickness of rub... and I cant hear the turbo barely.... and when I do, if I will let off itll stop spinning instantly. seems I have a few issues going on. checked mostly everything..boost leaks, fuel leaks. any idea where to start here guys? I had planned on new injectors this month coming but Im terrified to install new ones into an engine with other fuel/air issues.
Im thinking I need EFI live or similar to help diagnose this, and to check all is well when the injector job is complete. Thanks for any help
