Cylinder 3 misfire, burning oil/blue smoke, please help!
Hello, I bought my 2014 Ghibli SQ4 about a year and a half ago, and havent had many issues with it until today. I was driving around and all of the sudden it started to stumble and hesitate and the motor was shaky and rough, and the check engine light started flashing. I pulled over instantly, turned it off, and had it towed home. I then checked the oil to see if it was low. It was at the 'MIN' fill line, so I topped it off until it was back at the 'MAX' line. I thought that was weird, since I just got the oil changed 3 months ago (2,000 miles). anyway, after that, I did an OBD test on it and it gave me a P0303 code (misfire in cylinder 3).
Then, I decided to start it again to reverse it into the garage, but when I started it, it cranked for a long while and eventually started and still sounded very rough and the CEL was still flashing. Also, I noticed a good amount of blueish smoke coming out the exhaust while it was running for that brief amount of time. I also noticed a fairly strong smell of fuel coming from the front of the car.
so- given that I have a misfiring cylinder code, lowish oil, and blue smoke coming out of the back, its leading me to believe that some of the oil may somehow be leaking into cylinder 3 causing it to misfire and burn the oil.
The car only has 26K miles on it, I have not replaced the plugs yet. I am not exactly sure how I should go about fixing this....my plan as of now is to just replace the spark plugs and to replace the ignition coil on cylinder 3, and hopefully that will fix the misfiring (I have read that those are the two most common culprits for cylinder misfiring). The blueish smoke coming out of the exhaust is still very concerning to me though...
If someone has had a similar issue, or knows whats going on, or how to fix it, then please offer up any advice you can, I would really really appreciate it!
