My Jetta is cooked. Any advice?
Last summer, I bought a 2014 Jetta with about 55k miles on it. For about the first year of driving it, there have been no problems with it (other than faulty heating and regular maintenance). A few months ago my engine had a misfire which turned out to be caused by the spark plugs. After getting them replaced I thought I was in the clear. Sadly, I was wrong. My engine started misfiring again earlier this month, just one time though, and it was small. Took it to two mechanics, they both told me that they couldn’t tell me what exactly was causing it because they couldnt recreate the misfire, but the first mechanic ran codes on it and told me two possible culprits, them being the engine air/oil separator and the air intake boot. I decided to not fix them because I had to do my rear brakes anyways. I then experienced another misfire a few days ago, which seriously concerned me. I was delivering food and left the car in idle for a minute, when I came back the engine sounded unusually loud, and the exhaust was shaking pretty hard. I stepped inside and I could feel the whole car and engine shaking violently, tried to back out of the driveway I was in and could barely move the car. I turned it off for a few mins then it ran again just fine, with the check engine light staying on for a few mins before turning off. Finally we come to today. I was coming home from work when surprise.. it misfired AGAIN. Pretty similar to last time but with less shaking, and a new light on my dashboard which says “EPC.” I was also able to get footage of it this time. Im not a car guy at all and I don’t know about this stuff, has anyone experienced this before? Any advice? It would be greatly appreciated.
