Screwed into the head or heads. actually its not that easy to find the skylarks spark plugs. Just FIY one of them is under the alternator so have fun changin that one i know i didnt.
A 6-cylinder has SIX and a 4-cylinder has FOUR spark plugs.... Am I missing something here?
1 plug per cylinder so 6
the spark plugs are located on the front of the engine under the hood
I believe there is a slightly finned top on this motor (quad 4). remove the bolts on this and it should remove the finned plate, giving access to the spark plugs underneath.
I think it's .06 but if you get Bosch Platinum plugs, you won't have to worry about it.
It's a royal pain... The back plugs are the hardest to get at if you have a 6-cylinder engine. It's not impossible but you might have to rely on sense of feel. (Who designs these things anyway?)
Just follow the spark plug wires....
the oxygen sensor is located in/on the exhaust manifold.it looks like a spark plug with a wire coming out of the top
Remove the spark plugs wire and remove the plugs wit a spaerk plug wrench or socket.
One at a time
Check spark plugs and wires
