Hi I need to know how to change the spark plugs and cables on a 2002 kia sedona...I was told the first three were fairly easy to get to but the ones in the back are a bear...My mechanic says that I am having an issue with those as well as the timing belt..This is gonna cost me 1300 bucks...I would like to try to replace those myself if I can...I would greatly appreciate it...I need a guide to show me how to fix it as well if possible
Well, here it your delima. The intake manifold covers the back 3 plugs, You will need to replace those gaskets on the manifold as well. The only other thing I know is that there is a bracket on the back side of the motor. You must loosen it from the bottom. I would rather not see a novice do this with someone working closely with him.
The Timing Belt is probably an age or milage issue. A novice SHOULD NEVER attempt that. It the safest thing is to replace it. This way an old belt doesn't give out and do severe engine damage. I'm not saying it's going to happen. It's a gamble though.
That's the best advice I can give.

I had this same problem at 113,000 miles on my Sedona and I replaced the spark plugs and wires and it took care of this missing. It's an expensive job unless you do it yourself. However, the check engine light came back on so I have to replace the o2 sensor also. Here is a link to a tutorial on how to change the spark plugs. This is the best information you will find for changing spark plugs on a Sedona.
There are three on the front side of the motor, there are ignition coils and boots are each of them. Unbolt and remove the coil, they are down in the cylinder head, you'll need a ratchet and a 6 inch extension and 5/8 inch socket to remove them. The three on the back side are under the top of the intake manifold. You'll need to remove the top half of the intake to get to them.
The first three spark plugs are easy but the back three are not fun at all. You have to take the intake plenum off to get to the back three. It took me about 10 hours to finish the job. I don't even want to think about what the shop would have charged. Here is a link with the best directions you will find anywhere.
Do not attempt any maintenance on spark plug if engine is hot. 1. Disconnect negative battery terminal. 2. Carefully remove high-tension leads. 3. Use compressed air to blow any dirt or debris from around spark plug hole. 4. Check that spark plug fits squarely in spark plug socket and remove spark plug.
Raise a vehicle and install SST(OK552 131 001) in order to replace cylinder 2, 4, 6 spark plug.
Correct, its called the Plenum.... And it has to be removed.. you can loosen MOST of the things hooked to it, such as electrical plugs and EGR valve,ect and then "flop" it over out of the way.. you will need a new gasket for it before reinstalling it..
Sounds complicated, but it isnt...
If you want to see the three spark plugs on the back you have to lift your car and put on jack stand and follow the spark plugs wire under your engine. You have ignition coil set beside spark plugs for spare.
