Try swapping the coil from cylinder 1 to another cylinder and see if the problem follows it or you get a different code.

Cylinder 1 is the first cylinder on the right side, closest to the belt.

 

Sandstone-

Thanks I will see what that does later today when I wake up.

Ok so update...now it is apparently only doing this when my ac is on. Its been hot here lately so ac has been on all the time. Ac on almost instant misfire. Ac off smooth running. ????

 

There could be several things contributing or causing it, the easiest thing to try is swapping the coil packs.

I attached more info on troubleshooting the problem in a PDF that you can look through that will give you an idea of what you're looking at.

Hope this helps..

 

Sandstorm, he has C0301 Dtc and not P0301.

 

Hi Peter, thanks for pointing that out.

According to the manuals I have, "C" codes usually pertain to tire pressure monitoring, and there's no C0301 code specifically listed.

The OP was talking about a mis-fire, so that's why I offered the info on P0301.

@JRen , could you confirm the error code you're seeing is C0301 or P0301?

Thanks!

 

Look at the Link in my #4 Post.

Yes, I saw the link in your post.

But as I mentioned, that code isn't included in any of the Jeep factory service manuals I have.

Yes, it also mentions changing the spark plugs after 25 hours of use, where we normally suggest around 30k...
"Spark plugs typically need to be replaced every season or 25 hours of use. "



In any case, if the OP has a p0301 code hopefully the info I posted will help, and if it's C0301 hopefully someone else can help.

 

DAMN! And here I've been following the every 30K miles routine for plug changes. Based on my driving, looks like I'll be changing plugs about every 2 weeks or so...😢 Guess I'm lucky that the little 4-popper is quick and easy to get to, versus having to do 16 plugs on my Hemi every 2 weeks.😂

 

GUYs, Im no Jeep Guru but 25 hours.....If thats printed anywhere then its a typo! Its every 30k for both the 2.0 and 2.4 liter engines. 25 hours is simply ridiculous and if were correct there would be zero sales of the Patriot and Compass.

 

Or a HELL of a lot of spark plug change business going on!

 

And who knows how many hours a Patriot's been driven? It's not a tractor.
