SOURCE: car dies when driving,check engine light comes on.

There is a good chance it could be your fuel pump , however if the check engine light is coming on and the dealer cant tell you what is wrong , try a different dealer or another shop. Second opinions never hurt.

SOURCE: car chugging

To determine what's wrong, u need to have the codes read. If the light is coming on, it is a signal that something is wrong w/ the emissions system. A code is stored in the cars computer that will indicate what the problem is. Most parts stores will read the stored engine codes for free. They plug a scan tool into a port under the dash to retrieve the code(s). Write them down, and ask what u should do to correct the problem. If u have any further questions after that, u can post them here. Let me know how u make out.

REMOVAL OF THE PLUGS:

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. 

INSTALLATION:

1. Install spark plug into cylinder head.

Tightening torque : 18~22lb-ft (25~30N·m, 2.5~3.0kg-m)

2. Reconnect high-tension leads. 
3. Reconnect negative battery cable. 

Hope this helps and simple to understand. Good luck

How can i change my own spark plugs on my kia optima 2006


If it's a 4 cylinder then you have to remove the "coil pack" from the top of each spark plug. Should be a 10mm socket. then using a long reach spark plug socket, remove the spark plugs. Make sure to set the "gap" of the new ones before you install. Then re install the coil packs and secure them.

If it's a 6 Cylinder then remove the plug wires from the top of the plugs, then smae as above but you will probably use a spark lug socket and a short extension with the rachet, Once again be sure to "gap" the plugs before you install. best to do the plugs ONE AT A TIME, so that you don't mix up the wires.

2004 KIA OPTIMA WON'T START AFTER SPARK PLUGS WERE CHANGES


HI. There are several areas of concern here. I will list them below. Check all areas stated in the list for faults.

Possible cuases:

1. Incorrect firing order set. On the 2.0, 2.4 and 2.7 engines. These engines are equipped with a distributor-less ignition system. This system incorporates a coil pack assembly, along with wire sets. In order for the assembly to fire correctly, the order of the wires must be set to the proper sequence. if not, the engine will not turn over, or start correctly. Make sure your firing order is correct, and make sure you have not placed a particular wire set into the wrong cylinder. I will post a picture of the correct firing order for your engine, below this list, shortly.


2. Incorrect spark plug gapping procedure. If the new spark plugs were gapped incorrectly, this will not allow for proper spark, thus, preventing optimal combustion, due to lack of fire. Check the spark plug gap using a wire gap gauge, and adjust if necessary. The gap should be 0.039-0.043 in. (1.0-1.1mm)

3. Failed coil pack assembly. This will be the worst case scenario. The coil pack supplies the necessary current that fuels each plug. The current is transferred, via wire sets.This will be the culprit if all the above areas are proven to be operational, and in good shape.

4. Failed wire sets. Replace the wire sets if faults are found at the connector at the ignition coil pack, or at the plug boot.



NOTE*
In order to provide the correct firing order for your engine, i will need the engine size and liter information, if possible. Please post this information, asap. Thanks..

Where are the spark plugs located on an 04 kia optima


This is general car knowledge. An 04 kia probably has individual coils for each plug on the valve cover. Remove the screws holding the coil on the valve cover, gently pull/twist off (stuck like a cork) plugs should be down deep in cylinder head. Modern engines have iridium (100,000 mi) plugs. Yours could be this ,check the stickers in engine bay.

Changing spark plugs


hi there the reason you don't see the plugs is that they will be under a coil pack or separate coils go are the days of plugs at the end of the plug lead there could be covers over them be logical the plugs will be in the head normally between the camshafts if it twin cam.
hope this helps you Regards JR

Well i dont really know Optima's but the most easy way to find it is to find the spark plugs that go into the block of the car and then follow the wires to the other end away from the block of the car to the other end of the wires and thats where your coil packs will be. Hope that is some help
