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 plu gs. 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 rathe r 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' mea ns 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 cyl inder 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 w hether 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 switchi ng the coils on that bank also in order to find out if it's a coil, or wiri ng.
Thanks for any and all help.
