Kia cylinder numbering system
KIA 2008 Rondo 2.7 Liter V-6.
Still trying to solve my P0302 (misfire cylinder 2) problem. Replaced the three easy spark plugs, erased the codes, car ran fine for about 5 minutes and then the code reappeared. BTW, I also switched the three coils hoping the problem would prove a bad coil. Anyway, now I have to do major wrenching to get to the three back spark plugs. The on-line service manual has no information on cylinder numbering. Under specs. it does state that the firing order is 1-2-3-4-5-6 !! I rather doubt that unless they have a funny way of numbering cylinders. Called one dealer's service dept. and, after 5 minutes on hold they told me that cylinder number one is the one 'up-front'. I asked if 'up-front' means at the front bumper end of the car? Yes. I reminded her that there are 3 cylinders 'up-front'. Another 5 minutes and she told me it's the one on the end. Gently I reminded her that there are 'two' ends to this bank of three cylinders. 2 more minutes and she said it was the 'right' end, (that would be the furthest from the timing belts). Called second dealer and talked to service manager. Stated he did not know (he's honest!) and would I please hold. After 10 minutes he said that cylinder number one is front left as you face the engine standing in front of the timing belts. After all this effort I was too embarrassed to ask him whether the numbering thereafter continues straight back or zig-zag across. Do any of you know? I plan on tearing into it tomorrow. I plan on switching the coils on that bank also in order to find out if it's a coil, or wiring. Thanks for any and all help. Ivan Vegvary |

I've seen Kias try to accelerate. I've got a hard time believing their
cylinders are numbered anything other than 1, 2. </joke> -- Paul Hovnanian ------------------------------------------------------------------ Dedicated to the unrestricted propagation of worthless information across the Internet. |

I do have an OBD-II code reader (inexpensive HF model). Are you suggesting that a better reader would give me more detail than P0302? Thanks again. BTW a third dealer's service dept. confirmed the same cylinder layout that you had illustrated. He (service mgr.) said it took him 4 hours on the KIA web site (all the manuals are on the web for free) to find the info. I still can't believe, even with the layout you had sent me, that the firing order is 1-2-3-4-5-6. Having spent 50 plus years around cars, this would seem to be a very unbalanced firing order. Of course with computer control, maybe not. Thanks again, Ivan Vegvary |

A P0302 code means that the the car's computer has detected that one of the engine's cylinders is not firing properly. In this case it's cylinder #2. Symptoms Symptoms may include: * the engine may be harder to start * the engine may stumble / stumble, and/or hesitate * other symptoms may also be present Causes A code P0302 may mean that one or more of the following has happened: * Faulty spark plug or wire * Faulty coil (pack) * Faulty oxygen sensor(s) >>>>* Faulty fuel injector <<<<<<<< * Burned exhaust valve * Faulty catalytic converter(s) * Running out of fuel * Poor compression * Defective computer I was trying to suggest trying something simple and easy before busting too many knuckles trying to work on the rear bank of plugs, and that more than plugs/coils can cause a P0302 code.

Are you > suggesting that a better reader would give me more detail than P0302? Yes. A better reader, such as a laptop-based one, would give you most or all of the many engine parameters, which may help lead you to a solution.
