Hello everyone!

I saw this forum and thought it would be great to submit my issue with my 2003 Tiburon 2.0.

I have had a check engine light on for a few moths now. I waited for a bit to get the money I needed to fix the problems. There were a few. Upon those issues were a misfire in cylinder 2. I changed out the plugs and the spark wires. It ran great for about one month. The misfiring has started again, but it is not as frequent nor consistent. A friend of mine said it may be the ignition coil or the Crank Sensor. Can anyone confirm our speculations or have another possible cause?

It also does the misfire/hesitation more when the motor is hot as opposed to when the motor is first started and cold.

Thank you, everyone, for your help!

Is your check engine light on solid or flashing??? That makes a world of difference. Basically solid, is not to serious. Flashing is quite serious and should't be driven too much. Who told you that there wa a misfire on one of the cylinders?? If you took it to a garage, did they fix it?? Did they clear the codes?? If the light is on solid, you can pull the negative terminal off for a few minutes , so it cancels the code, they start it back up again. Did you use the right plugs?? You can have a dead new plug, it happened to me. You should always use factory wires, they are the best for your vehicle. And they are worth the extra money. Have you done a lot of driving?? Maybe you got bad gas, that has happened to me to and when I changed the filter on my 2001, a red oil substance came out of the filter..Serious. Always start with the easy things.. It could be the coil block, but your garage can pinpoint that for you. One test you can run, have the vehicle running, then pull off a plug wire at a time. Use heavy leather gloves or an insulated pair of wires or something similiar. then you will know for sure if it is a plug wire, plug, or coil box. I hope these help ya.......
