It sounds like he's got problems. I hope I'm not being to technical with my diagnosis.

:icon16:

Maybe his knock sensor is kaput so the timing is totally retarded.

whats a knock sensor and where can it be found? cuz i never heard of one...

I don't think it's the knock sensor. If he's redlining it in 5th gear, the car should be going a helluva lot faster than 60. Clutch? Tranny? Inaccurate info?
