If coils replaced and still shaking suspect something else like a guibo going bad. Don’t be surprise that bad engine mounts can cause shakiness as well. Good luck buddy.

Good call. I think it's the rest of the coils. Might as well swap them all with new ones. Plugs are all new (3-4 months old). I checked dealership servicing papers and saw that coil 3 was replaced but the indy mechanic found coil 3 to be faulty?

However, if you are having issues with the same cylinder after doing a new coil and plugs, then start looking into other reasons why you might have a misfire. It could be bad injector. If you replace injector and problem is still present, then you would need to do a leak down test to see if your compression is right. If your compression is off, then you might be looking into a bigger issue - bad engine. |

Just to make sure, there are 8 coils in a V8, right? Just checked a quote from the last mechanic for replacing all 8 coils, but QUANTITY says 6.

I had the same issue a few times on my 2016 f36 n20. Only happened like 3-4 times within 2 years. Went away every time I restarted the car. Happened once to my new 2018 x6. Both cars had piggibacks installed. Could be related?)

Thanks everyone for your input! Finally found a trustworthy mechanic and got everything resolved (the previous mechanic was just... confusing). One of the coils was faulty; mechanic replaced and test drove and runs smoothly, but asked to replace the rest since it's just a matter of time before the other ones start going bad!
