- Thanks to all who responded to my questions about the O2 sensor--
-
- I replaced mine last night and well, I have a new car for $37. This has
- solved a very long (3 year), annoying problem with my '87 Integra. The
- car has been to all Acura dealers in Minnesota... with each one replacing
- various major components (computer, idle control valves, throttle body)
- and doing all sorts of tuneup things like injector cleaning, new plugs, etc.
- None of which made any improvement. They are clearly unable to diagnose
- these sorts of problems.
-
- I spent 10 minutes with my multi-meter measuring the voltage from the O2
- sensor and it was totally fubar. The Acura service manual states that
- you should get a voltage of less than .4v at idle (after fully warming
- the engine) and something greater than .6v at open throttle. I was getting
- totally random readings at idle-- sometimes .1v sometimes .9v... it would
- always settle out to some value but each time I opened the throttle and
- then closed it, it would settle out to a different value... anywhere in
- the range .1v to .9v. At open throttle, it read close to 0v... *all
- screwed up*.
-
- I had called Acura yesterday just to check their price:
- They want $130 for the sensor and $26 to install it. But they don't
- stock them. Fools... I asked the service manager there if
- they ever have these O2 sensors go bad-- he said NEVER... They have never
- replaced one and that's why they don't stock them. FOOLS!!
-
- I got mine at the corner auto parts store (A Bosch one-wire unit) for
- $36.99 and then $17.99 for a O2 sensor/temp sending unit socket... (it
- has a slot cut down the side so it fits over the connecting wire
- properly). After 30 minutes of fumbling around (15 of which was spent
- waiting for the manifold to cool down)... I had it replaced.
-
- The difference was immediately noticeable... the car idles like it did
- when it was new! except, now it has 86K on it. The idle is rock solid
- and doesn't oscillate between 850 and 500 RPM like it used to. Accelerating/
- decelerating are smooth as can be... rather than the choppy/surging kind
- of thing it used to do. It's zippier from a dead start and it just plain
- sounds like it's running better (psychomechanics ?? :-) ) Anyway--
-
- I am truely grateful to net.wisdom and all the folks who provided details
- about operation and testing of O2 sensors... You've given me my car back
- and great peace of mind. Thank you.
