do the map sensors fail .my car is 19 years old with original sensor.
is it worth buying new one in the hope it will fix the misfire.

A poster has already suggested it could be the map sensor. You can at least check it is clean. It is a simple part. Failure is going to create a code.
Have you checked the codes?
Meanwhile you seem to be ignoring repeated requests to you to find out if you have checked the ECU earth.
