The governor pressure sensor is the most likley cause however an inspection of fluid or debris in trans pan would be a good idea to make sure there's nothing excessive in it. Attached is a list of possible causes however the senor would be the most common.

POSSIBLE CAUSES

• Powertrain control module
• 5 volt supply circuit open
• Check transmission fluid level and condition
• GOV press sensor signal circuit shorted to voltage
• GOV press sensor signal circuit shorted to sensor ground
• GOV press sensor signal circuit shorted to ground
• GOV pressure sensor signal circuit open
• Sensor ground circuit open
• GOV press sensor signal circuit shorted to voltage inside transmission
• 5 volt supply circuit open inside transmission
• Intermittent governor pressure solenoid
• Internal transmission problem
• Oil burnt or oil pan has excessive debris
• Other transmission DTC'S
• GOV press sensor signal circuit shorted to sensor ground inside transmission
• Valve body
• GOV press sensor signal circuit shorted to ground inside transmission
• GOV press sensor signal circuit open inside transmission
• GOV press sensor ground circuit open inside transmission
• Governor pressure sensor (high)

I'm going to guess since you didn't mention which fluid...Transmission?
First find out which unit you have (usually an id tag on it somewhere ) Then look up what kind and how much fluid in your owners manual (usually around four quarts...unit holds more but you can't remove it from the pan) Remove all pan bolts and lower pan. (some units have a drain plug, use it first if you have one ) you will see the filter attached to the valve body. remove it and install the new one, Make sure all gasket material is removed from pan and trans. Clean any metal etc from pan and internal magnet (there is always some in there but should not be a ton of it) Then put pan and gasket back. Make sure you can turn each fastener easily to make sure they are not cross threaded and only tighten them after they are all in there. Bolts do not have to be tightened down like they never should be removed again (snug then a little bit more)tighten in an X pattern not a circle.Replace about half of the fluid with car off, then put in remainder while running. Put your foot on the brake and shift to reverse then drive a few times then check fluid level.Low is bad, a tiny bit (less than half inch) over is OK.
Drive for a short ride, check again for leaks and re-tighten if any are found.
If trans was exceptionally dirty and yours has a drain plug, I recommend that you use a generic oil on the first change, then in a week, drain oil again and re-fill with good brand name stuff. and perhaps a bottle of lucas conditioner.
Good luck!

Check the fuses for the overhead console, could be that if not then the console needs to be replaced.....

If you haven't changed the plugs or had the fuel system cleaned, now would be a good time to do it. The number 1 culprit for rough idles is dirty injectors or plugs. You can try an injector cleaner in a can (or bottle) for under $10 and see if it helps, and then work from there. If there isn't any improvement then if you are able to, check the plugs for any gunky buildup and if you find a bad plug, make sure you replace them all (or have them replaced) at the same time.
