How Much Money Should I Be Willing to Pay to fix my 2014 Jeep

Caught the Bug
I changed a 9 month old spark plug and the original coilpack on #4 cylinder to see if this would get rid of the CEL. My 2014 JKU Sport is 11 years old (152K miles) with the 3.6 engine so I've been having nightmares about her needing work. I was going to try new fuel injectors to see if that will fix everything but trying to not throw parts at it. P0304 and P219B. I want to get a compression test but I am concerned about the cost of the repair if it turns out to be the 3.6 common problems with rockers and lifters. I did the above mentioned work in front of my apartment by myself so I was very proud of myself. If the cost is more than $2500, should I consider not spending that much money on an 11 year old Jeep? I've researched this 3.6 issue and new about it but I've read estimates between $2K-$6K. I just want my Jeep to be enjoyable again. One shop charges $125 for a compresssion test and then $500 to remove the valve cover to diagnose. Yeah, the shop will put the $500 charge towards the repair but who knows what the estimate will be. A dealership here charges $225 for the diagnostic but who knows the repair estimate will be at a dealership. Some guidance would be appreciated. This is my second Jeep and I've driven a Jeep for the past 20 years. I was spoiled with the inline 6 on my TJ and loved it.

will be interested in knowing if you your mileage improves, idle smooths out, as well as performance (though it'll be seat in the pants)

The JKU seemed to have more pep when starting after being at a red light. I put in a bottle of Lucas fuel injector cleaner and used mid grade gas after the repair. My girl is 11 years old and I'll need more time to see if idle smooths out. I have low expectations for skyrocketing MPG because I do drive a brick. Bonus points if MPGs goes up.

Glad you got it fixed and followed up with a good read of the process you went through to get there.

Like I said. I’m no mechanic but I get a lot from this page so I thought I would contribute an ending to my story and pass on info. Enough people used JL injectors in JKs successfully that I was willing to try. Thank you for reading my update.
