Engine Performance problem
1986 Honda Civic 4 cyl Two Wheel Drive Manual
so i have a honda civic 86 si. the problem is the ecu shoots me error code 0401 disconnect map sensor piping. so i replaced the map sensor and it worked for a day and then it was back to acting the way it was. it was hesitant and the car would jump up and down. i get bad gas mileage and i was running on the rich side. so i got it timed replaced the ecu and spark plugs. but none of that worked. so back to square one. im thinking its a vacuum leak, pcv valve, or egr... so what could it be??
