if you don t see any spark plug wires then your motor has coil packs(black colored boxwith 2 small electrical wires) located on top of motor 3 on one side,3 on the other.disconnect negative terminal on battery,then disconnect wire connector at each coil pack and remove 2 screws that hold down coil pack, pull gently straight up and plug is right there below coil pack

I have a 98 dodge intrepid with a 2.7. My car would run fine at times and then all of a sudden start to miss badly and the valves would rattle. The mechanic changed the cam shaft sensor and now it runs very well.

Changing Spark Plugs

First off, on this model you don't have plug wires, you have coil packs with a boot and coil connected to the pack. The boot slides on the tops of the spark plug. The good thing about this is that you don't have to mark each wire to its location.

So to replace the plugs you need to disconnect the electrical connector to the coil pack and then unbolt the two bolts that mount the pack down, then remove the pack.

Next with a ratchet, an extension and a special spark plug socket, which has an insulator inside to protect the porcelain from getting cracked, remove the spark plugs.

Next step is to replace the plug, usually I slide off the boot from the coil pack and then remove the coil from inside the boot and slide the boot over the spark plug and start to thread the plug back in. Using this method allows to you feel if you are threading the plug in right. Then with a torque wrench you would torque the spark plug to the specs for the type of engine you have.

Next reinstall the coil pack with the two mounting bolts, it is only necessary to hand tigthen the two bolts. Then plug back in the electrical connector and continue this process on the next 5 spark plugs.

To remove the map light bulbs you need to first remove the overhead console.

To do this you need to remove the screw at the front of the overhead console (which is more towards the front windshield).

Next you need to pry down on the rear of the overhead console and then disconnect the electrical connectors.

Then, with the overhead console pulled down, pull of the map light bulbholders and replace the bulbs.

Installation is the reverse of the removal process.
