does anyone know where cynlinder 4 is on a 2004 sonata located? getting a code P0304 misfire #4
First, we need to know if this is a 4 cylinder or a 6 cylinder engine.
What is the maintenance history of this car?
Number one cylinder is generally the one closest to the timing belt, timing chain, harmonic balancer, etc.
Find your ignition coil pack or distributor - look at where the wires connect - look for numbers with each wire. Find number 4 and follow the wire.
thanks guys but i found it. 1 3 5
2 4 6
The firing order for a 4 cylinder engine is 6 positions!!! Wow!!!
never said it was a 4 cylinder car. you are asked the make and model of the car when you submit your question and i clearly stated this it is a V6 2.7 sonata. number 4 cylinder is the middle bottom,toward the fender
Actually, that information did not appear anywhere in this thread until you posted it a few minutes ago. That is why my first response on this thread asked you to clarify whether the car has a 4 cylinder or a 6 cylinder engine.
and i truly thank you for our help in even replying to me. once again thank you
I hope it is in the engine.
i fixed it , lol # 4 is right in the middle, thanks again
Who said it was a 4 cylinder?? By the firing order it obviously is a 6. But for my info, Is 135 on one bank and 246 on the other. I know that Chevrolet used to, and probably still does, numbered the cylinders alternately between the banks, #s 135 on one bank and 246 on the other. Ford, however, numbered the left bank 1234 and the other bank 5678 ( on a V8 of course).
thank you for your help and you are right it is a V6 and the firing order for a 2004 hyundai sonata is 1-2-3-4-5-6. number 4 is the front middle. hope this helps someone . thanks again for your post to me
“the firing order for a 2004 hyundai sonata is 1-2-3-4-5-6”
Ummmm…I don’t think so!
Posting misinformation like this is potentially harmful to other Sonata owners.
okay, Here are three!!! sources that says i’m right. where do you get your information from? 1) my 2004 manual section 9 page 3 2)http://autorepair.about.com/library/firing_orders/bl-fo-0300.htm, 3)http://www.automotiveforums.com/vbulletin/archive/index.php/t-694119.html
the firing order is 1-2-3-4-5-6
you have gone around the issue. this is likely an instance where all the plugs and wires should be replaced. it is expected that if one plug/wire has gone bad, the others arent far behind. while there, replace all of them, then you have eliminated this as a problem for the next 60k or so. just doing the ONE is counterproductive.
ToBeCaptured is correct. The firing order of the 2004 Hyundai Sonata 2.7L V6 engine (6 cylinders) is 1,2,3,4,5,6. The even numbered cylinders, 2,4,6 are on the radiator side [the engine sits side-wise], and the odd numbered cylinders, 1,3,5 are on the firewall side.
So, WHERE is #4 cylinder? And, is it easy to work on #4 spark plug? I think that we’re, finally, starting to get somewhere, don’t you? I’m glad to be of help.
For those who wish to see the information, go to www.autozone.com, register, and enter the vehicle you are interested in.

All V-6s with which I am familiar had vastly different firing orders.
The GM engines with which I am familiar had–IIRC–either 1-6-5-4-3-2 or 1-4-6-3-5-2 for their firing order.
My Taurus used a 1-4-2-5-3-6 firing order, I believe.
My Subaru H-6 has a 1-6-3-2-5-4 firing sequence.
Obviously Hyundais are a horse of a different color, and I have learned something new today.
If you look at the cyliner numbering, you’ll see that on the Hyundai V6 engine that the cylinders fire right bank, left bank, right bank, left bank, right bank, left bank. If you look at the cylinder banks of the Ford and GM engines, you’ll see that the firing order goes from bank to bank to bank, won’t you?
