It should be warmest at the thermostat. I don't know the coolant path in the 4.0 but I would think the coolant would start at the back of the engine and move forward toward the T-stat. Now combustion temperatures in each cylinder being fairly even and the heat transfer rate being even the...

I kind of figured it out after posting. For coolant temp I would say just put it in the upper coolant pipe. The difference in temps throughout the engine won't be but a few degrees C.

For Oil Pressure do what Cal said and use a T fitting in the stock location and for oil temp you can either attach a thermocouple to the dipstick end or drill a hole in a drain plug and put in a fitting. Those are the ways we measure the temps where I work.

You get the bolt and the adjuster that bolts to the back of the idler pulley at the dealership for about $25 if I remember correctly.

Sounds like the fuel pump. I am pretty sure O2 sensor high voltage means it's leaning out. We had one recently same year and everything that you described it did and it turned out to be the fuel pump.

It is a bad sending unit mine does the same thing and it is a 2000. Also it is a very common part to go bad. Should be $40 at a dealership, don't think they sell them at Murray's or Autozone yet.

Unplug the black connector from the ECU under the hood for a few minutes. This will clear the ECU's memory so you will know if the problem is fixed or not.
