It's one on the firewall side of the V6 transverse mounted engine.
Dealership suggests replacing all 6 spark plugs and the 3 coil on plug coil packs on the bank towards the firewall since it is a real pain in the ass to do. $1350 (Thirteen hundred and fifty dollars!) and she'll be good as new.
Long story short it made it back to Texas with an intermittent check engine light and she had an Indy do the work for short of $700.

You can insert any brand and any dealership here. This has nothing to do with Lexus. Dealership fix > Indy fix > DIY. In that example, you could have put a new single coil pack on DIY for $80 and be on your way ...
Edit: a basic OBD reader is under $30 ...
