it depends on how far it is off . sometimes it requires removing and repositioning the distributor. if it is not much you may loosen the bolt that holds the distributor down and adjust the distributor left or right in order to advance or retard the timing. you will also need a timing light and a grease pencil preferably white in order to mark the timing scale on the flywheel pulley with the right degree for your car. usually two people are better than one since the vehicle will have to be running and always be careful leaning over a running motor not to catah your clothing or body parts (be carefull).

The speedometer on a 1990 Mercury Topaz may not be working due to a faulty speed sensor, a broken speedometer cable, a blown fuse, or a malfunctioning instrument cluster. It is best to have the vehicle inspected by a qualified mechanic to diagnose and fix the issue.

the timing is usually set by adjusting the distributor and using a timing light on the number one cylinder and pointing the light at the harmonic balancer on the bottom of the engine crankshaft pulley,the timing mark on thr balancer should be marked on the correct degree for example 10 degrees before top dead center. as the distributor is turned the timing on the light will adjust to the balancer . to get the correct timing look under your hood for a sticker that has timing and sparkplug gap specs.
Most likely speedometer cable
The 2.9 liter V6 engine in a 1990 Ford Ranger has a timing CHAIN
Chain and it is a very (~1000.00) costly fix.
If timing is bad on a 1990 Acura Integra they car will either run incredibly rough out not at all. To fix the timing be sure to correctly align the distributor to the right factory specified degree.
If it is working what needs to be fixed? Assume, the lack of display. Not sure but I think the radio has two separate fuses, one for the radio one for it's display, check the fuses I have had similar problem but not sure if it was with my Topaz
To fix the horn on a 1989 Mercury Topaz, first check the fuse and relay related to the horn in the fuse box. If they are not the issue, the horn itself may need to be replaced. You can access the horn by removing the front bumper or wheel well liner to reach it.
