What year is your car, how many miles? Do you have a K&N filter? If so, did you recently clean it?

Make sure all your spark plug wires are "clicked" on.

Have someone run a msifire test on all 8 cylinders.

I have the same problem right now. I'm hoping it's not the coil pack cause I'm broke and christmas is right around the corner. Switch the coil pack to another cylinder and see if it follows, if yes, then it's the coil pack.

Simplest way to ID the missing cylinder is through the scanner, watch the misfire counters. Once you know which cylinder it's just a matter of checking spark and fuel to that cylinder, and that there is not a vacuum leak close to that cylinder (misfire at idle) If the cylinder has adequate spark and fuel, that only leaves compression (valve timing will not factor into a single cylinder misfire)
