If striking the dashboard encourages or clears the fault then either a bad earth or bad solder joints on the membrane sheet behind the dials.
How far off is it? Did you change tire/wheel size? Bad speed sensor.
There are 2 sensors on the engine that sent a signal to the computer and speedometer and tach. When one of these goes bad it can make the speedometer and tach go all over the place and also just stop working. This can also cause all types of engine running problems because the information being sent to the PCM will be incorrect all so. The units are easy to replace once you find them, it seems that they are located in different areas of the engine with each year the vehicle was put out. Your local dealer should be able to tell you the location of each sending unit. .AnswerIf your speedometer is not working, it is probably the speed (distance) sensor. There are tons of sensors. Follow the speedometer cable down to where it attaches to the sensor...Unplug speedo cable, pull elec plug, remove 10mm bolt, pull out, replace is opposite. (This is not the same sensor as the input or output sensors)
Recommended size is 14" to 15". You can go higher to 16" but not recommeded. Note that when you go for bigger rim, the profile must be adjusted accordingly so that the speedometer stay the same. Otherwise the speed recorded in the speedometer is incorrect.
A parallax error is when the experimenter reads or record incorrect measurement of a quantity.This may happen because he/she does not know how to read the instrument and can be prevented by learning to read the instrument correctly.
NO, that size is incorrect and is not an optional size. Use that size and your speedometer will be way off. Look on the door post for the correct size.
A cack is another word for a squawk, or a discordant note, caused by, for example, someone playing a brass instrument in an incorrect manner.

some are. there are 4 bolt and five bolt saabs. if the tire sizes are the same and the same number of bolts then they are. otherwise there will be ride problems, handling problems, and your speedometer will be incorrect.
The speedometer does not take into consideration the size of the tires. It measures the rpm's of the transmission or differential. **incorrect, the speedometer uses a predetermined constant based on the circumference of the stock tire diameter multiplied by the number of revolutions** I suggest driving alongside a friend who can signal you when his speedometer reaches predetermined speeds according to the speed zone and check your own speedometer to determine the speed you need to drive for that speed zone. Do this on a rural road with no oncoming traffic to avoid any accidents.
Incorrect firing order, spark timing, cam timing, or intake valve operation.
Yes, it is an instrument for recording. A microphone is a sensor device that converts mechanical pressure waves or sound in air into electrical voltage waves. Speaking into a microphone excites (moves) a diaphragm that is coupled to a device that creates an electrical voltage proportional to the produced sound pressure.
check for clogged fuel filter, incorrect or improperly gapped spark plugs, or ignition timing
