Question about 1990 Honda Civic
I have a 1990 Honda Civic 5 speed. We have replaced the engine,distributer, distributer cap, O2 unit,ignition modular, muffler, cataletic converter, it is timed properly, new spark plugs & wires. We have put on 2 different throttle bodies, check vacum hoses for leaks and nothing seems to be helping. We are getting about 19 miles to a gallon. Idles very high even when warm. The engine light comes on after the engine is warm.
The engine light is on, Have u checked for fault codes? To check codes, pull back carpet on passenger side of car to expose ECU (electronic control unit) at 'foot' location on that side. There is a small LED display at the top of the unit, turn the key on (not running) and check for flashes, u must count the flashes to determine what codes are stored in the computer. Short flashes are for codes 1-9, two digit codes use long flashes for the 1st #, followed by short for the 2nd. There is a pause between codes, so there may be more than one. Check and let me know what u find.
