SOURCE: 1997 Honda Civic EX power loss
start with the easy stuff. check the plugs. make sure they are not wet with oil leaking from the spark plug stem seals located on the rocker cover. Check your air filter to make sure its clean. Now for the slightly harder stuff. The spark plug wires should be changed every 80k or so. My suspect the reason for the power loss is most likely a clogged cat convert in the exhaust system. check your exhaust flow. Way to do that is to check the temp. of the exhaust before the cat and the temp. after the cat. If the Cat is plugged the temp before the catalytic converter will be abnormally higher than after the cat.
BUT if you are experiencing misfire of engine. I would go straight to replacing spark plugs and wires. Distributor cap and rotor.
Also check the charging system. make sure the alternator is charging the battery at above 13Volts. With all components on. ( radio/lights/highbeam/AC). Use a voltmeter and check at the battery positive and negative. if its not charging above 13 V replace the alternator.
