    Oxygen sensor voltage?

    Okay, I'll see if that works. Give me a minute.

    Oxygen sensor voltage?

    Do you mean force the lead into the same hole that the wire goes into on the female connector? Sorry, I'm not good with electrical terminology.

    Oxygen sensor voltage?

    Hmm. So I shouldn't even try this without that? I guess you can get this at a Chevy dealer? Also, I was looking at this test: http://www.veryuseful.com/mustang/tech/engine/images/o2SensorTests.gif And it appears to be for a newer mustang, I think. My connectors only have 3 prongs...

    Oxygen sensor voltage?

    Okay, I'm trying to test at the ECU for o2 sensor voltages. I don't see where to put the positive prong. There is a large gray female connector that goes to the ECU. I'm assuming it needs that plugged in to run, so how would I test for voltages? Pierce the insulation on a wire?

    Oxygen sensor voltage?

    Yeah, The vacuum didn't seem to change during this. It was almost like the car controlled it. Very strange indeed. Any likelyhood of one of the intake manifold gaskets leaking? They've never been off the car. I don't know how I could test for those, spraying fluid on it won't work because...

    Oxygen sensor voltage?

    I was using an analog meter. I had the setting on 2.5DC volts. The needle never moved when I touched the prongs. I thought it was supposed to if the sensors are working correctly?

    Oxygen sensor voltage?

    Also, an unrelated question. While I was running my car at idle while it surged, I noticed a hissing sound just like a vacuum leak, although it could be almost anything whooshing. I would start hissing and then stop all by itself, then start again. It sounded like it was coming from somewhere...

    Oxygen sensor voltage?

    I've been spending some time lately trying to figure out why my oxygen sensors won't turn on. I borrowed an analog voltmeter to do these tests. I tested the main harness plug that hooks into the oxygen sensor harness. One of the prongs was putting out 5V. So I assume that's the heater. I...

    5.0 coupe or 5.0 GT hatch- please vote

    I've got a red 93 coupe I'm thinking about selling. It's got 75,000 miles on the 5.0 and the same for the rear end, and about 30,000 on the clutch and rebuilt T-5. The reason for less miles on the T-5 and clutch is that it used to be a 4 banger and the doner car was a 93 Auto... so the T-5 was...

    314 stroker??????

    314 would be kind of a waste of buying a new crank, wouldn't it?

    And are you ever going to feel your o2 sensors for me? :D

    whats the point of having O2 censors????

    I was just joking... I wasn't trying to come off angry.

    whats the point of having O2 censors????

    You want your oxygen sensors, unless you like your car running pig rich at cruise, part throttle, and idle. If you also like paying a **** ton for gas all the time, then by all means, take them out. Over the last week I've been pulling my hair out trying to get them to work. So do me a...

    What would Happen?

    It would probably rev way past its limit until the valves float where it would all destroy itself.
