- I specifically looked for and tested this issue... I plugged and unplugged
- the OLD sensor many times and made certain that I had the best possible
- connection to the sensor wire and to ground when I was taking the readings.
-
- With the input to the computer grounded, the motor idled very well... when
- I reconnected the OLD sensor, the idle began to oscillate and roughen within
- seconds. This behavior seemed logical given the erratic readings I was
- getting on the voltmeter from the O2 sensor. I was working at the
- sensor end of the wire rather than the computer end. The sensor had
- about a 10" pigtail (single conductor) before it hit a connector. It was
- at this connector that I performed my checks. The contact inside the
- connector looked clean and bright and I scraped the meter probe back
- and forth many times to ensure a good connection.
-
- I'm willing to bet my next paycheck that there wasn't an intermittant
- connection.
