No the speed sensor will not cause misfires at higher speeds and this sensor is located on transmission case up high and towards the tail shaft Not in the tail shaft that one is the vehicle speed sensor and it sets a po500 code.
There is an idle advance sensor, which increase the idle speed when the A/C is switched on, to stop the car stalling on tick over because of the load the A/C pump puts on the engine. The sensor may be giving wrong information to the ECU.
This is most likely 2 problems. The ABS/Brake light and speedo issue will be the speed sensor located in the read differential housing. The temp guage issue (and I'm assuming this is at idle) could be thermostat or temp sending unit. The fluctuation is causes by the electric cooling fan cycling on and off to control the temp. However, most of the time this fluctuation should be from about 195 - 220 degrees.
SPEEDOMETER (SPEEDO DRIVE) IS USUALLY LOCATED IN GEARBOX NORMALLY SCREWED IN SMALL BOLT YOU WILL PROBABLY FIND IT AT REAR END OF GEARBOX AS FOR RPM DIAL THAT IS USUALLY WORKED THROUGH CRANKSHAFT SPEED SENSOR BEFORE YOU GOCHANGING SPEEDO DRIVE MAKE SURE ITS NOT A BLOWN FUSE
I would look into replacing the VSS which is the vehicle speed sensor, it is the input that tells the transmission when to go into overdrive and the torque converter to lock up, also make sure the connector is clean and tight to the sensor, this part is located on the side of the trans where the speedocable would go.
