Engine Mechanical problem
1995 Honda Civic 4 cyl Front Wheel Drive Automatic 205100 miles

OK. I have a 95 civic EX 1.6 liter. My engine light is on so I purchased an OBD1 code reader. I tested it and test indicated MAP sensor. I tested the sensor, its good. What are other likely problems my car may have? The issues my car seems to have include; significant reduction in mileage(from 30mpg to 22mpg highway), overheats sometimes(only in idle position), coolant disappears but goes nowhere(not leaking and not in oil, it just evaporates), a lag in acceleration. Please help. Thank you

If you got a code for the MAP sensor, 9 times out of ten, the MAP is faulty.

Test to ensure there's a 5V reference and ECM ground on the harness connector. If there is, replace the sensor.
