I need to know how to change the spark plugs on my 96 ford contour
A set of spark plugs usually requires replacement after about 20,000–30,000 miles (32,000–48,000 km), depending on your style of driving. In normal operation plug gap increases about 0.001 in. (0.025mm) for every 2500 miles (4000 km). As the gap increases, the plug's voltage requirement also increases. It requires a greater voltage to jump the wider gap and about two to three times as much voltage to fire the plug at high speeds than at idle. The improved air/fuel ratio control of modern fuel injection, combined with the higher voltage output of modern ignition systems, will often allow an engine to run significantly longer on a set of standard spark plugs, but keep in mind that efficiency will drop as the gap widens (along with fuel economy and power).
When you're removing spark plugs, work on one at a time. Don't start by removing the plug wires all at once, because, unless you number them, they may become mixed up. Take a minute before you begin and number the wires with tape.
Be sure not to use a flexible extension on the socket. Use of a flexible extension may allow a shear force to be applied to the plug. A shear force could break the plug off in the cylinder head, leading to costly and frustrating repairs.

REMOVAL & INSTALLATION
Fig. 1: On some later models, it is necessary to remove a cover to access the spark plugs
Fig. 2: Carefully twist the boot end of the spark plug wire .
Fig. 3: . . . and withdraw the spark plug wire boot from the cylinder head
Fig. 4: Using the appropriate sized spark plug socket, necessary extensions and drive tools, remove the plug from the engine — the spark plugs are usually 5⁄8
Fig. 5: After removing the plug from the engine, inspect it using the spark plug condition charts in this section to determine the running condition of your engine
Fig. 6: When installing the plugs into the engine, start the plugs by hand. A piece of hose or rubber fuel line makes this job easier
Hope this helps and please don't forget to rate!

need to know what engine u have
so do i need to join you ?
