I have a 2003 hyundai tiburon with the 2.7 v6 thats having all 6 cylinders misfire. It started after I changed the spark plugs and wires. Ive taken the steps to make sure they were the correct spark plugs and wires and made sure the gapping on the spark plugs were correct. Its not a spark problem cause ive already tested that as well. I even doubled checked with a local garage to make sure that the wires are going from the correct coil pack to the correct cylinder. Any suggestions on how to solve the problem?
