P 0301, CEL flashing, losing power on freeway
I've done some digging on this great site (always had my prior problems diagnosed and had great help) and didn't find my exact problem.
2006 Jeep wrangler, 2.4L, 6 speed manual.
Lately, it has been running a little rough, low rpms at idle, but seems to run fine at street speeds.
The Check Engine Light occasionally flashed on the freeway, but lately I've not had a lot of power (just on the freeway; surface roads seem fine) and have had a hard time maintaining freeway speed, even in 5th gear. (If I put it in 6th, the speed just slowly drops.) Tonight, the check engine light was flashing, and then stayed on. (That's new.) I pullled off the freeway and found a parking lot. I turned the key off and on 3 times (which I learned here), and got P 0301 as the error code. That's apparently the Cylinder #1 misfire.
I found a few threads here that have outlined all the things that could cause that code. I'm hoping that the issue of the freeway loss of power could help point to one or just a few issues to narrow it down.
Any ideas or suggestions? If there are other symptoms that might point to one or another, let me know and I'll try to narrow it down.
Thanks in advance for any efforts to help. I really appreciate it.
Strength and honor.
