Re: Code P0301
What all is in the 'everything" that was changes 6 months ago?
That doesn't mean one of those new components cannot be the problem now. As
with anything mass produced... occasionally a defective part gets through or
one fails early.
I think my first move would be to pull the spark plug from the #1 cylinder
and examine it carefully for signs of a misfire.
At this point you could swap it with any of the other spark plugs
(preferably #6) to see if the code moves to that cylinder or you can just
spend the $2 and buy one new plug.
If that fails you can try spraying a MIST of water around the coil rail.
sparkplug boot area while watching and listening for a spark leak. This is
best done away from shaded or dark area.

That doesn't mean one of those new components cannot be the problem now. As
with anything mass produced... occasionally a defective part gets through or
one fails early.
I think my first move would be to pull the spark plug from the #1 cylinder
and examine it carefully for signs of a misfire.
At this point you could swap it with any of the other spark plugs
(preferably #6) to see if the code moves to that cylinder or you can just
spend the $2 and buy one new plug.
If that fails you can try spraying a MIST of water around the coil rail.

It is possible you don't feel anything because it is a in-line 6. A
missing spark would probably go unnoticed, at least for a little while
until you get problems from fuel in the exhaust. Before I had my YJ's
original 4.2 I6 replaced, I pretty much had ziltch compression on my
number 6 cylinder and I hardly noticed it unless doing 70+ on a steep
(for a freeway) incline--then it felt like I was driving my mom's '81
Honda-civic-putt-putt.
On the 4.0, the sparkplugs fire twice per cycle as 3 ignition coils are
shared by the 6 cylinders so you may want to also look at the other
sparkplug that's tied to the number 1 cylinder's sparkplug.
If you ever look at the engines that are used to demo the snake-oil
additives on late night infomercials with sand and other crud dumped
on top of the heads, it's always a I6.
You should still check your plug and anything attached to it.

It is possible you don't feel anything because it is a in-line 6. A
missing spark would probably go unnoticed, at least for a little while
until you get problems from fuel in the exhaust. Before I had my YJ's
original 4.2 I6 replaced, I pretty much had ziltch compression on my
number 6 cylinder and I hardly noticed it unless doing 70+ on a steep
(for a freeway) incline--then it felt like I was driving my mom's '81
Honda-civic-putt-putt.
On the 4.0, the sparkplugs fire twice per cycle as 3 ignition coils are
shared by the 6 cylinders so you may want to also look at the other
sparkplug that's tied to the number 1 cylinder's sparkplug.
If you ever look at the engines that are used to demo the snake-oil
additives on late night infomercials with sand and other crud dumped
on top of the heads, it's always a I6.
You should still check your plug and anything attached to it.

Why away from shade or dark areas?
