95 E150 gauges acting strange
95 E150 4.9 I noticed my coolant gauge fluctuating and abnormally high then I noticed my oil pressure really high. When I give it gas from a stop the oil gauge goes all the way up and the coolant gauge moves a quarter inch in either direction.
The charging and gas gauge seem to be normal, charging gauge may be slightly low.
Any clues

first of all, econoline gages are notoriously inaccurate.
second, there is a component called the "instrument voltage regulator" mounted on the back of the instrument cluster, and when it fails, it usually causes the temp, oil, and fuel gages to all spike together. a problem with it WILL cause the 3 gages to make similar changes at the same time, usually in the form of excessively high readings.
you may also want to attach a voltmeter to the system to determine if your charging system is putting out too much voltage. the easiest way to set this up is to use a little guy like 12 Volt Battery/Alternator Tester , just plug it in and drive. i use mine all the time on various systems, its simple and reliable.

Although my fuel gauge isn't acting erratic it may not be moving as much as it should.
I briefly checked the ground from the battery and that one seems to be fine. It does have the original alternator 170,000 miles. Dunno.

I spent a lot of time with wiring diagrams, other grounds and checking voltages but the main battery engine ground was the culprit. This ground is very hard to get at since it is buried back from the front right lower engine block corner......
