1995 Nissan Sentra GXE 1.6
Summary:
Great, reliable economy car
Faults:
Check Engine Light Has come on and off intermittently. No problems ever were diagnosed. Unknown why the light went on and off.
At 130000, A/C hose broke.
That's all!
General Comments:
For an economy car, the car has enough pep with the manual transmission to climb all, but the steepest hills and pass most cars when needed.
I have had this car for 140,000 miles and have done no repairs other than brakes, and a few small minor repairs which probably have not totaled $700 for the life of the car.
Would you buy another car from this manufacturer? Yes

I would suggest replacing that oxygen sensor. That is an important one. If you do not change it, your car will never go into "closed loop mode," where the computer interfaces with the oxygen sensor, to fine tune the air/fuel mixture for optimum performance and economy. Your car is therefore always running rich, in the mode it would-be/is during a cold start.
Another possibility that might arise out of not fixing this, depending upon the severity of the situation, is that you could damage your catalytic converter, a very expensive fix. If you are experiencing a rotten egg smell, it is too late.
On a '95 front wheel drive 4 cylinder, the oxygen sensor should be a very easy fix, which you can do yourself. It should be right on the exhaust manifold. You will have to buy a special oxygen sensor socket/wrench to get it out.
Disconnect the negative battery cable before you proceed. Take your time and study the connector for the oxygen sensor to see how its locking/clipping mechanism works. DO NOT FORCE THE CONNECTOR APART. Once you figure out how to disengage the clip mechanism, the connector should come apart with just the force necessary to separate the connector ends from their weather packing/seals.
Then, just unscrew the old oxygen sensor, and replace it with the new one using the reverse procedure from above. Be sure to leave the negative battery cable disconnected for 10 minutes, to assure that all existing trouble codes (hopefully only the oxygen sensor) are erased.
One additional piece of advice, is that in this case, although it costs more, get the new oxygen sensor from the dealer. After market oxygen sensors are complete crap compared to original equipment. Replacing it should be no more difficult than replacing a spark plug. It is ridiculous how much people want to charge for doing something so simple. I would consider giving it a try yourself.
