Have you tried spraying crc into the distributor cap

Check the ignition system,when one of these goes out it take out another cylinder,you hhave a misfire,

you do need to remove the upper intake plenum to replace the rear plugs. haven't found a easy way or special tool for the job.

do a compression check , and check spark at all the plugs with a inline tester, should tell you what you want to know

1st check quality oil and filter, if oil and filter is good, then remove engine oil pan , clean oil pump strainer, instal oil pan , add new oil and check.
if have oil on spark plug inside of cylinder, you need to overhaul the engine, if oil is over the spark plug ,change the valve cover gasket

replace spark plugs, spark plug wires, cap, ignition rotor, air filter, oil change, transmission flush, transmission filter&gasket .. That should do it.. It'lI be good if you could check your timing as well.. do this tune up every 15-20 thousand miles and oil changed every 3000 miles, depend on how much you drive it.

Hi!

You need New Spark Plugs, Spark Plug Wrench Socket and Wrench Extension (at least 2-3 inch) size 10 socket and/or size 12 socket.
First of all, please check where the spark plug cover is. Once you figure that out there will probably be size 10 or/and 12 bolts holding it down. Take that off and there you will see sensors connecting to each other and holding the spark plug in the cylinders. Unplug all the sensors and pull out the circular plugs holding the spark plugs down. Pull them out and make sure that you don't drop anything into the cylinderes. You can look down into them and see the spark plugs. Get your spark plug wrench, extension, and socket wrench and stick them down in and push so that the spark plug wrench grabs them. Then unscrew the plugs, pull them out and put the next ones in and tighten them down. Just connect all the sensors, and put the cover back on.

Thanks for using FixYa and do rate if found this solution helpful.
