Drove out to scottsdale tonight and the check engine light came on again

Says error p0300 and p0306

P0300 is Multiple Cylinder Mis-fire and
P0306 is CYLINDER #6 MISFIRE

I havent noticed any issues driving, no stalling or backfires. Ill take off the spark rail on friday and put in some new plugs. Hopefully that fixes the issue

pulled out the spark plugs on friday. Pretty easy to to do

I pulled off my air intake tube to make it easier.

The newer TJ's replaced the distributor with a spark plug rail. This is bolted onto the side of the engine block and is easy to remove



After thats out just use a 5/8" spark plug socket to pull out the old plugs, then put the new ones in and bolt the plug rail back down. Its a quick and easy job. Took me 30 minutes

Heres a pic of my old plugs. They did have some corrosion on them
