Customer Question

I have P0016, P000B P000D, P0018, and P00546 codes I went through some water recently, and these codes surfaced. It is running very rough as well. Multiple cylinders misfiring
JA: Have you metered out the ignition system?
Customer: I have not. How does one go about doing that?
JA: What is the model/year of your Jeep?
Customer: 2015 Wrangler JKU
JA: Are you fixing your Wrangler yourself? What have you tried so far?
Customer: I am looking for possible causes and/or worst case scenarios. I will likely take to the dealer, since my local guy said it may be a severe problem
JA: Anything else you want the mechanic to know before I connect you?
Customer: That should be it
