What is this sensor?

What is this sensor? Car is 96 gtb. I unplugged it thinking it was one of the O2 sensors to see if my low rpm pinking/crap performance problem would go away in limp mode. However no CEL or any difference in peformance warm or cold.

Is that water on your swaybar or oil?

[funkytown]

it is an oxy sensor. that one in the manifold is a funny/special/retarded one.. but i cant remember exactly why

you probly have another one on the top of one of the down pipes

[KarlGTB]

Thats oil, not sure if its from a recent spillage or leaky rocker cover.

Theres this sensor right down the bottom of the down pipe or...

looks like wires going into the downpipe about half way down but cant really see it with the intercooler still on

I think it probably should really go on a select monitor rather than me attempting trail and error, but i've wasted my money twice with muppets that come back to me with "well theres no codes". Anyone can check the codes, but who in wellington can actually check that the sensors are performing properly for a resonable cost?

The first one is your oxygen sensor.

The second one is the cat temp sensor. The light on the dash tells you when the cat is overheating.

If the cat blocks up you'll have low exhaust flow, and low heat. The engine will choke when you try to rev it.

As for the light and wiring, it all depends on how the circuit is wired as to what you earth and what you leave open circuit.
