The Beginning of the Issue
This is my personal story about my 2015 Jeep Wrangler and that annoying check engine light that’s been with me for four years.

It all started shortly after my adventure on the Rubicon Trail in July 2020. I was in Texas on my way to visit my niece. It was scorching hot and humid. During a pit stop, while enjoying some tacos with the AC blasting, the check engine light came on. The code…P0306 – Misfire in Cylinder 6.

Troubleshooting Attempts
I tried everything to fix it:
- Replaced the spark plugs
- Swapped and replaced the ignition coils
But nothing worked. Given my financial situation and some personal challenges, I decided to live with that little light on my dashboard.
For the next four years, I drove another 45,000 miles with the check engine light on. It wasn’t ideal, but it was the best I could do at the time.
The Final Diagnosis
When I moved to Cheyenne, Wyoming, I decided to have TNT Customs take another look. They tested & swapped everything again and more.
- Fuel injector
- Ignition coils
- Spark plugs
But the misfire in Cylinder 6 persisted. They ran a compression test and found 50 PSI in Cylinder 6 compared to 156-160 PSI in the other cylinders. The verdict…Time for a new engine.

The Solution
At the time, there was a waiting list for a Jasper remanufactured 3.6 engine, I was number 5 on the list. However, at that time financially, I wasn’t ready. Recently, I got lucky and found an engine that would work at a reasonable cost.
Sometimes life throws you curveballs, but with a bit of patience and persistence, you can find a way through. Definitely, a lot of patience on my part.
Now my engine is gone replaced with another 3.6L the guys at the shop I worked at helped me find. They did a great job putting it all back together for me. Now on to more items to fix in my Jeep.
