Thanks for all the input!

This girl has not been getting her exercise. Upon inspection the plus/plug wires were orginal. 94k mi & 31yrs on the original plugs & wires. Replace those and a nice italian tune up/hill climb and she's better, but still a little rich.

Can anyone point me to where the three temp sensors are? I replaced the one at the rear of the right head to get the temp gauge operational & I know there's one single-pronger on top of the thermostat housing. Which one is that & where's the other one?

Thanks.
