Subject: No Power
Question:

I have a 1995 3000GT SL 3.0 manual, the car runs but doesn't seem to have the power it should taking off, a friend told me it may be the o2 senor going bad. any ideas?

Answer: Marshall,
This can be caused by a number of things. Usually a bad O2 sensor won't cause this particular problem; and you would most likely see your check engine light come on. This problem is typically caused by a clogged air intake, clogged fuel supply, or improperly set ignition timing. All your engine may need is a simple tune-up. Have your mechanic check your intake and fuel systems, along with the ignition timing.
Good luck!
