So just for some background, I got my 2015 VT April 31st of this year. Orange, has all of the options and had 49xxx when I bought it. At roughly 51300 now and have had my fair share of problems for less than two months of ownership. Got a misfire two weeks after buying it, didn’t drive it until we got some new plugs and a new ignition coil for it. It fixed the problem, but idle seemed different from the first startup after the changes. Almost exactly two weeks after that, another misfire happens. First time it was on cylinder four and the last time it was on cylinder three.
This time, I got all four ignition coils, which are Delphi’s and change all of them when they come in. Fixed the problem but idle shake consists. That was May 3rd. I live in Missouri, and it’s been raining nonstop for the past week and have definitely noticed a difference in how the car pulls and idles now with the increased temp and humidity. Before the past week, the idle shake was really only noticeable if the air was on, but now, whether the air is completely off or AC is on I feel it. It does it no matter what. I have a video of the engine bay and how much it shakes with the AC on and off. I have put on a K&N Typhoon intake and also a GFB bov in, which I installed a week after the first misfire was fixed.
Another thing I noticed recently was the intake noise-it’s more like if you have pressurized air and blow a piece of paper back and fourth instead of a constant flow. Only happens in higher rpms, around 4.5k or so. I could also get a video of this to better describe/show it.
One more thing I thought I should include is that it is a one owner car and it has had no accidents and maintenance was all done on time from what I could see and match up with the manual.
I apologize for the book, it’s just that I have had terrible luck with cars and went out of my price range hoping this car could last me for atleast a couple years. Thank you for your time!
