I was watching Dr 914s walkaround of a D Jet 2.0 motor, and he makes a comment that the Cylinder Head Temp sensor causes a lot of problems, and can get wonky.
Is it possible for one to test out fine (2750 ohms) and then act bad? I have a strange syndrome where the car was running fine, but developed a rich syndrome very suddenly. Haven't had a chance to check it again, but it was almost new. TIA Rob |

Might check the CHT wire to the ECU also. Do you have a known good MAP to cross check? Or carry an ohm meter to check the sensor output next time it gives up the Ghost. These type headaches are why I converted to water cooled. (IMG:style_emoticons/default/headbang.gif) GL
