Replaced the Temp Control Sensor this after noon, reset codes and no problem, the Knock Sensor was reading incorrectly because the temp sensor was out, go figure it would kick another sensor off when it died. all is well with my baby again, though dammit now i have to have the engine cleaned again got some greese on the intake manifold, when i removed the wire there was greese in there, i probly have the cleanest engine in the world most people cant believe its and 89.
