Can someone please tell me what resistance I should be getting from my 3 prong sensor when the engine is hot and when it is cold. I've been getting 60 ohms when it was cold, warmed the car up a little bit then got 82 ohms. Took it out for a good warm-up and when I returned got 60 ohms again. Now it seems to me that I should be getting some different readings. Of course I'm having some performance problems with the car as it seems to be running rich and I'm having some starting problems, answers? I'm pretty sure that the problem is narrowed down to this sensor...
