Well I have replaced the ECT... and will be doing the plugs & wires in a few days. We'll see how that does.

Also, half of my daily drive is highway driving and my OD is out, so thats not helping either.

I tried to replace the temp sensor for the trans but I cant find one ANYWHERE! Even the Mitsu dealer acted like I was from another planet.

On the other hand I noticed that the temp sensor never makes it towards the middle... and I wonder if a previous owner put in a non-OE temp thermostat?
I think OE is 190* and I have seen some marketed for the Monty at 160*... could it be that simple?

Happy to be here, and happy to be back in a classic Montero!
