Repair Questions and Answers
Question: 1991 Nissan Skyline GTS I-6
mileage: 58,000. My question is this. I have been having
some trouble with my car sputtering very badly. It
really acts like it is not burning all the gas. I
changed the spark plugs and fuel filter. This did not
help. Then I changed the 02 sensor. This did not help
either. There is a really bad exhaust smell, like
un-burnt fuel and there is some really black suit all
over the back of the car. The car does not run hot, but
the exhaust pipe is hotter than normal. One time
recently the catalytic converter light came on. Could it
be a problem with my ignition coil or something else? I
am sure that the fuel is getting there ok, but I just
don't think it is being fully burnt. Please help. Any
help or advice you can give will be greatly appreciated.
Thank you
Answer: Check the fuel pressure
regulator as it may be hanging up causing excessive fuel
pressure. Also, Check the catalytic converter as it may
be partially plugged.
