I have a 2003 hyundai tiburon 2.7 V6 and the engine gets herky jerky during acceleration I have a cold air intake and have had to clean the mass air flow sensor a few times but it doesn't seem to be that I had this type of hesitation in the engine before and the check engine light came on and the code was missfire so I changed the plugs and wires and it was fixed but this time its not as bad and no check engine light whatcha think ,thanks justin
