How do you replace sparkplugs?

I looked at Alldata under spark plug removal and ignition coil removal but they had no useful information. Autozone have some popular workshop manuals for free on line once you register (for free) on their website http://bit.ly/autozone_repair_infoThere is a company that independent auto repair shops "buy" their information from that offer a very reasonable service to do it yourselvers. You get a one year subscription to year make and model specific repair procedures, service bulletins, component locations, wiring diagrams ect.... great quality information same as the professionals have ,much better than generic workshop manuals from parts stores, much cheaper than the factory manual. http://bit.ly/alldata_repair_manuals or try http://bit.ly/mitchell_repair_manuals_online and get an online repair manual subscription.

Your plugs are found under what looks like valve covers. Two bolts hold down these covers. Alot to remove like hoses or if you can twist the cover around.Air filter canister must be removed. Then you will see the coils, 4 in a row, because one for each cylinder right:) Be careful now and unclip the wire harness connector to each coil;Do not confuse which connector goes to which coil/cylinder.With fingertips reach as low as possible around coils, they are round and have long rubber insulators attached to tip of spark plugs.You may have to work these alittle to remove. Now you are down to the plugs.PLEASE be sure the engine is cool!!! The plug is steel where as your cylinder is aluminum. You know what happens with two different metals, right!!!?? And dont strip the threads in the block either!!
