Question about 1997 Oldsmobile Silhouette
Car running ruff and gas milage has gone from 24 to about 10 miles per gallon
Remove the plastic coil cover from the middle of each valve cover. Remove the coils. Unscrew and remove the spark plugs. Installation is the reverse....
If you have wires, you have three coils and not six and you've actually got wires. To remove one end of a wire, first twist, then pull. If it won't twist, use spray silicone lubricant.
You may have a large plastic beauty cover over the top of your engine. If it's in the way, remove the four nuts and the cover.
