Misfire Cylinder 2 and 3 Kia Picanto

Asked by: 10 views Engine Question

I have a Kia Picanto 2004 with 113000 km, petrol, and 1.1 engine and the engine light is on and the ODBII reader says that it is a misfire in cylinder 2 and 3. The mechanic changed the injector coil and no change. We checked the spark plugs and wires and grounding cable and they are good. I put fuel injector cleaner in and no change. If the A/C is on, the car looses some umph. What do you think it could be? I am scared to take it to the mechanic again and get charged a lot of money for them just checking stuff..

    I would start to inspect the crankshaft sensor for any cracks on the sensor.
    Did they replace the spark plugs within the coil replacement?
    I would erase the trouble codes and drive it more and see which trouble codes are coming back.

    Misfires could be due to a lean or rich fuel mixture also.

    Thank you for the response. I did turn off the light and the same error kept popping up. This weekend, we unplugged the battery to reset the computer and it seemed to run a lot better, no misfiring even tho the error kept popping up. Also, now when I turn the A/C on, it lags…
