So i have a 2000 Civic ex. When it starts up, it runs fine but then after it gets warmed up, it starts to die when i push the clutch in. It idles at about 800 rpm and then when the clutch is pushed in it dies. Then when i try to start it again, it takes a few times to get it running. Any idea what it could be? Could it be the spark plugs or something? Some one said it might be the MAP sensor.
