Its shaking alot, already replaced wiring and sparkplugs. on the computer it shows that its misfiring. what can it be? 2003 grandam

u might have a loose plug boot or a bad coil pack or plugwires are on tyhe wrong plugs.check the firinfg order and follow from the coils to make sure, and check the boots for snugness, if you can pull them off easily then there not attached properly.

Cant find sparkplugs

The spark plugs are under the aluminum engine cover plate on the top of the engine. ( The one that has the raised ribs and has the 2.4 on it) You need to remove the 4 bolts that hold the plate on the engine and then you will see the spark plugs in the center of the head in between the cam towers. Once you get the plate off, you can't miss them.

Missing on one cylinder

Replace the coil going to that cylinder, and then replace the valve cover gasket to prevent further oil from getting on the new coil. If it is not the coil, the crank sensor could have gone bad in it.
