In our trip across country, the check engine light came on in our 2000 Kia Sephia. We checked all the fluids and engine temperature is normal. But when you push the gas it sometimes jerks into gear, i think it's the spark plugs but can't find them to check them in the engine. please help us!
Optional Information:
2000 Kia Sephia 4cylinder
