There are apparently 2 Oxygen sensors on the vehicle as it is OBDII.
I do not want to throw parts at it believe me, I started with the cheapest possible and worked my way up, now its getting expensive.
I am familiar with use of a voltmeter what is the voltage range I am looking for?
Why do I need a blow torch...?
you move the blow torch across the o2 sensor, it simulates lean/rich mixture and you can watch the 02 sensor sweep back and fourth between rich and lean to make sure it is functioning. This is not something I would rec. in a college dorm/apt setting. Also in an OBDII situation the secondary sensor is worthless as far as engine performance. All it does is take readings after the cat to make sure the cat is functioning properly. If you took it out and plugged it with a bolt all it would do is set the dummy light. Also as a word, I would say get the proper OEM primary o2 if you firmly believe it is the culprit. I find the "universal" ones tend to be more trouble than they are worth. If you are interested I can find out what my price on an OEM o2 sensor is and if it would be worth it to you etc..
