Hi.
I have a 1995 Honda Civic LX, with about 120, 000 miles on it.
I was experiencing somewhat lower gas mileage and some loss of power (especially on hills) for a while, when my 'Check Engine' light came on and stayed on about 1-2000 miles ago. Checked code, and it pointed to the Oxygen Sensor as the problem.
I bought an 'Universal' Oxygen Sensor off Ebay and installed.
Have had in for about 500 miles now, and this is what I observed since installation:
1) When I installed the new part, I had 2 black, 1 white and 1 green wire on old part, and end of the sensor (about 1" long) had several holes (about 10?).
New part had 2 black, 1 white and 1 BLUE wire, and only 2 holes at the end.
I attached the green wire to the blue wire (had to splice the wires), and installed the new sensor. Question 1 - are either of these items a problem?
2) After installation, I thought I would have to disconnect the battery to reset the computer system, but did not have to do! When I started up the car, the light was off!
3) The first night I drove the car, no problem with light coming on... but the next morning, after about 10 minutes of car warming up, the light came on. I have since then observed that light comes on every time car sits long enough for engine to be cold, and then will come on after about 10 minutes of car warming up! All I have to do is to turn engine off and light goes away, and does not come back on again, until I let car get cold again!
What could be the problem? Note that I have noticed better power on hills now, but have not seen any improvement in gas mileage, maybe even less!
Thx.
