Thanks to Tegger (cylinder firing order) and to the rest of you I solved my misfire problem. Took the 2nd cylinder spark plug boot/coil assembly and swapped it with the adjacent cylinder (#4). Yup, the misfire code changed to P0304.
Had a hard time finding the coil. Everybody shows it, no body carries it. This Kia Rondo (2.7 liter V6) must be a very low production number -or- I' m the first one needing to replace a coil. NAPA couldn't find one close th an Texas, Car Quest finally found one at their store in Bakersfield CA.
In any case, installed the coil, re-set the code and the car runs like a Sw iss watch.
Thanks again for all of you that replied.
