Postby 92strokersmoker » Wed Jun 22, 2011 3:17 pm

I found mine when I pulled the head off. Well, tried to. It came forward about 6 inches and then stopped. I was like, WTF? What's that wire? Awww, siht! :(

I was lucky, I bent the plastic and cracked it. I checked it with the multitester and it show continuity so I put some silicone in the cracks and ran it. It works, so I got lucky. 8)

I must be thinking of the wrong thing. (where is the smacking the forehead smilie?) Im thinking oil, not coolant.

I got a question, I noticed that the wire going to the sensor comes out of the harness that also has the wires for the speedo. Both my speedo and coolant temp guages are giving me eratic readings, my temp guage just goes hay wire at a million miles an hour along with my speedo. Im wondering if its a bad ground issue but I keep looking for grounds and cant find any. The ones I know of look fine. Before I drop money on a new sensor, Do ya'll think it sounds like a wiring issue or a sensor?
