The engine on my 1999 Buick LeSabre will not go off. It has recently had new spark plugs and wires added

SOURCE: Check engine light comes on,

The Chilton and Haynes manuals show pics of the spark plug wires in the tune-up section.

SOURCE: rough idle

fuel filters rarley cause idle problems. i would look at the egr valve or possible vaccume leaks.

SOURCE: Hesitation during aceleration

You may have a vaccume leak

Pick the one below that matches your coil pack orientation. There should also be cylinder numbers on your coil pack.
