Bad cpu?
My oil pressure gauge reads 30 at 1500rpm idle and like 60 @ 2200rpm warmup. Is that the normal?
anyhoo... my coolant temp gauge is not reading and the system is getting warm because it idles down, it has that annoying buzzing with the red led lit all the time. it also says i need to add coolant, but the system is full and has no air in it.
My headlights wont pop up, no wiper movement, fuel level gauge not reading...
are these symptoms of a bad cpu like in the 1st gens or do you think i lucked out and have a crapload of sensors broke?

CPU = body computer
The Body computer has nothing to do with oil pressure gauge, coolant temp, headlights, wiper, and fuel gauge.
Also the ECU (engine/emissions computer) would not have anything to do with any of those problems either.
Oil pressure is within limits.
Don't understand what the heck you mean with the coolant temp idling down, but the buzzer and red light indicates that you have low coolant in the radiator (don't confuse this with the overflow tank). If the coolant system has not been properly bled when filled, you will get a low coolant trigger. If the gauge is not working, either it is unplugged at the sensor, or you have a bad/loose screw connection at the back of the gauge cluster.
Headlights not coming up is either a bad headlight switch or more likely a bad headlight relay.
Wiper's not working are either a bad wiper switch or bad wiper motor or disconnected linkage.
Fuel gauge not reading is either a bad sensor, bad gauge or bad/broken/disconnected harness (usually at the back of the gauge cluster) or a loose screw/bad connection at the back of the gauge cluster.
