I took everyones advice and pickd up a scangauge. Apart from coolant and oil temps what other things should I monitor.

 

Monitoring FICM voltage is a must. Other than that, whatever strikes your fancy. I like to watch HPOP pressure, MPG, and will probably be setting up the trip computers on my next long trip. Be aware that when you are setting up ECT, the special X-gauge for ECT reads in 2 degree increments, while the stock gauge for coolant temp reads in 1 degree increments. I don't know which is more accurate. Charge voltage seems to read .2 - .4 volts low of actual battery voltage.

Voltage and if towing, the tranny temp. I also have the icp on page 2.
