RPM/Speedometer/Fuel Gauges gone crazy?
So sporadically this last week, when I drive.. the RPM gauge will go crazy, dropping to 0, then up to 3000, and anywhere inbetween. but the engine sounds fine, it's not actually doing these things, the gauge just says it is. As well the speedometer goes from 65, to 0, and anywhere in between, but I'm maintaining a constant speed(65).
I remember about a year ago my fuel gauge doing this, and it hasn't worked since. It doesn't show how much gas I have in the tank. It is always on empty according to the gauge, but I'm usually at least 3/4 full. My gas gauge will show when I'm on empty, the yellow gas tank symbol will light up, but it won't ever show how much gas I have in the tank via the gauge.
Anyone know what is causing the gauges to go crazy? Sometimes the speedometer/RPM works normal, sometimes they go crazy. How do these systems work? is something loose? Any help is appreciated.
Regards,
John

RE: RPM/Speedometer/Fuel Gauges gone crazy?
So I checked all the grounds I could find. some of them under the hood, were a little rusty. So I undid them, took a wire brush to them until there was bare metal all over, and I put them back. Still the same problem though.
Bad96_3.9, where is this plug? I have to take out the instrument panel..and there is some plug behind there?
