The engine is a 2.4L. My apologies for missing that in that title. I got the battery July, 23, 2022. I started my car to do a load test on my battery, and I had a code for a cylinder 1 misfire. I swapped coil 1 to 4 and the engine light stayed on and the same cylinder 1 misfire code was there. The load test came out to have 14.78 the highest and then it would surge down to 12.15 and bounce in between there. I can’t read the alternator with my meter leads when my car is on the ground. The alternator is hard to get to.

I have a 13 journey, high miles. We had a bad storm in Ohio, after the storm, I noticed my car battery died. I charged battery, my car turned over and gave me a rough idle, all my lights were flickering. I had a cylinder 1 misfire, I bought all new Bosch Platinum pre-gapped plugs and installed them. I took my battery out and charged it inside and measure 12.6VDC before I put it in. I started it up, the engine light is gone but I still have a rough idle, rpm’s bouncing and all my lights are flickering. I have videos but it won’t let me upload them. I’m lost at this point, and like most others on here funds aren’t really there to take it to the dealer.
