I'm having the same issues after having the ignition coils replaced by my local indie shop...and am 1200 miles away riding out the COVID19 quarantine with family, so can't return to the shop that did the work to address care what should have been done already, everything's closed, and the shops here are way overpriced anyway.
Could you please describe the needed tools and how to access the ignition coils/plugs so I can check and tighten as needed myself?
Thanks so much.
