on my 97 the cause was the cam position sensors, there are 2 it cost me $500 at the caddy dealer
you dont need to cause it has a factory tachometer
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.

There are several things that can cause your engine to misfire and the tachometer to not work properly. The most common cause is a malfunctioning vacuum hose.

My 89 jeep Cherokee surges at idle and sometimes stalls but runs fine once you are going what could cause this?
I would say the mechanic didn't re-install the tachometer wire ,whereever it goes on this motor,which I don't know. I would say the mechanic didn't re-install the tachometer wire ,whereever it goes on this motor,which I don't know.
