Hey all, Long time lurker, first time poster! I have an issue with my 2016 SV6 SII where it seems to idle rough when stopped almost 90% of the time I drive it (whether it's when I first turn it on, at a set of lights or stopped in traffic). It feels as if there are cars going past me causing the entire car to shake, but it happens when there's nothing else around (I noticed it when I was waiting for a car wash yesterday it just randomly started doing it). I've taken it to the dealership twice, they were able to replicate it the first time I took it in, but the second they weren't (that's another story though, I'm fairly unhappy with the service from this particular dealership). After the first visit (where it was happening intermittently at this point) I was told to try using either 95 or 98 exclusively, but it's made it worse to the point it's happening 90% of the time I'm idle. Does anyone have any experience with a similar issue and can maybe point me in the right direction so I can relay the info to the dealership? Thanks in advance!
