no it will not!
replace the ignition coil. There is a resistor inside the coil that fails over time and causes 2 problems. 1 the transmission may fail to properly lock the torque converter and 2 will cause the tachometer needle to fluctuate wildly, esp when it is hot outside.
yes
Could likely be a dying battery or bad alternator. I would have your battery checked out. This just happened to me and turned out that my battery was bad.
yes it can.
you dont need to cause it has a factory tachometer
According to auto experts, the main causes of motorway accidents are driving too fast and faulty observation. Also, driving too closely is another major cause.
A short in the turn signal wiring can cause the voltage gauge to fluctuate. A loose ground wire can also cause the gauge to fluctuate.

If the engine sounds loud like it's going faster than you really are it could be that you have lost your overdrive gear in the transmission. Once you hit freeway speeds, the automatic overdrive kicks in. If the engine seems to be operating normal, your tachometer might be faulty. Ken
A bad ignition coil can cause your 1987 Acura tachometer to quit working. A bad tachometer cable or ground wire can also cause it to quit working.
It goes up while driving and down when you're idle....that's normal
Having a short in the turn signal wiring can cause gauges to fluctuate. If the battery gauge is fluctuating corrosion on the cables can be a possible cause.
