Cant find spark plugs - 1999 Oldsmobile Alero

try a pair of plyers and try to wigle it , if needed pull hard on it

fuel filter may be on backwards, restricting fuel flow, if not that check that the spark plug wires are on in correct firing order, as well as the spark plug gap. (spark plugs are not always gapped for the particular application from the factory due to the multiple array of applications a particular plug can be used for)

Leaking fuel injector dumping fuel so fast it cant burn off flooding cylinder

Pull a spark plug wire off a spark plug, insert a screwdriver into the plug and replicate a spark plug gap using the screwdriver against the valve cover or something that has a ground connection. Have someone crank the engine over while you check for an arc with your simulated spark plug/screwdriver.

USE A SPARK PLUG WIRES BOOT PULLER.THE BOOT PULLER CAN GO TIGHT PLACES WHERE YOUR HANDS CANT REACH.ONCE YOU REMOVE SPARK PLUGS WIRES REPLACE THEM.SOME PLUG WIRES WILL BREAK AWAY FROM THE BOOT WHEN REMOVING SPARK PLUGS WIRES.DONT REMOVE OLD PLUG WIRES IF YOU DONT HAVE NEW SET PLUG WIRES ON HAND.BECAUSE YOU WILL DISABLE VECHICLE.IF COUPLE OLD PLUGS WIRES BREAK WHILE REMOVING THEM YOU WILL BE 2 PLUG WIRES SHORT AND YOU CANT DRIVE VECHICLE THAT WHY HAVE NEW SET OF PLUG WIRES ON HAND.

your spark plug wires have a rubber boot on the end of them and some times they come off and stay on the spark plug to where you can't get the socket on the plug. If you have oil on your plug wires than you need to replace the valve covers. You can use a long thin screw driver to get the boots off the plugs. It may take some time but they will come off.

get a spark plug tool and put it over the spark plug and twist it counter clockwise then replace it with the same type of spark plug then twist it clockwise until you cant any more

you have to access the spark plugs from the wheel well.

The spark plugs are under the 4 spark plug wires.
