Car has ran fine for months without a problem, put gas in it last night after driving it 10 miles with no issues and when I tunred the car back on I am getting CEL 3 and cel 9... they literally came out of no where... anyone have any ideas? I am checking the map and plugs and wire harness when I get at work, I just dont want to have to get a dizzy but if I have to, I will. Any help is apprecaited. in a 91 civic RTAWD wagon.

    god I feel like such an idiot, I checked everything, the map sensor, the dizzy, all vauums, spark plugs and everything and it still didnt go away. Pulled my carpet up and one plug from my ecu was very loose and when I pulled my ecu out the plug came out, clipped it back in and everything works just fine!
