However my suspicions run elsewhere. the turbo MIGHT be failing but it's replacement would be last on the list ( a used one goes for about 100 -200$) The First thing i would check is the turbo plumbing. ie the hoses that come off the pressure side of the turbo. if a clamp on the plumbing has fallen loose or the rubber has developed small holes in it this could cause intermittent power problems. the next thing to look for is the Hoses that go to the apc system (The APC system is not contained within the turbo but is a component of the turbo. there should be vaccum lines that run off the turbo into the apc wastegate.) these vaccum hoses have a short life and with a small leak could cause performance problems. A good repair manual (even haynes has info on the turbo) should help you to fix it caution is necessary. READ CAREFULLY and WORK SLOWLY
