how to locate and chage plugs
if you have the 2.2 liter ecotec engine, they are located right on top of the engine, they are located under the top black piece that says ecotec on it.
By checking fuel injector or the spark plug I had the same misfire on my 2001 alero and now it works grrat.
Their is no 1993 olds alero the first year is the 1999 sorry.
6 spark plugs 1 spark plug to every cylinder.
It is located over the cylinder head.
The 1993 Oldsmobile Cutlass 3.1 liter engine spark plug gap is .028. Most spark plugs will come pre-gapped from the manufacturer.
The spark plugs are on the front and back of a V6 (back ones are tough to get to) L4 right in front. Turn the engine off and take off the spark wires unscrew the plugs
on my 2002 alero I havw the 2.2 4cylinder ecotec engine, on the intake there is a cover that says 2.2, remove the four bolts and the plugs are down in the little cylinder holes mine require a 5/8 spark plug socket and you will also need an extension.
For the 3.4 V6, it : 0.060 inch (1.52 mm)
where would the spark plugs at on a Oldsmobile 1989 engine
on a 2002 olds alero 2.2 4 cylinder ecotec the spark plugs are located on top of the intake, under the cover that gives the engine size,it is possible that yours may also be located under this cover. All you have to do is remove the four bolts on top of the cover and your plugs will be under there.
Totally depends on engine. If you dont see them right off, your are most likely located under the big valve cover similar to the hemi engines of Chrysler.
