This post is related to getting an ODBII code of a cylinder #2 misfire on a 2000 RX300 which primarily sits today in a garage and never driven. SUV has around 100k on it. Easy to do with proper tools and a bit of patience.
ODBII shows P0302 - Cylinder 2 Misfire Detected
A few months back mentioned this vehicle and using a fuel / oil add on to maybe clean up the fuel and oil and hopefully get rid of the ODB II code. That didn't work anyways cuz SUV has not been driven in the last 6 months anyhow.
Last year replace the rear hatch door struts and put a new battery in the vehicle. (5 year battery $92 - struts $30)
Will leave cover off and do this in pieces with front cylinders first with one session and back cylinders maybe one at a time.
1 - 6 spark plugs (from Amazon) ~$30
2 - 6 coils (coil pack from Amazon) ~ $65
Total here is < $100.
Thinking average for this little project is around $600 including parts (just a guess).
Basically here just replacing the coils and spark plugs. There is a cover on the engine with 3 allen screws to remove first.
- remove 3 allen screws
- twist lexus logo and lift cover up

Spark plugs and coil packs are located here
- cylinders 2,4,6 are in the front
- cylinders 1,3,5 are in the back
Each coil has one allen screw holding it in place and the spark plug is under the coil.
Back three cylinders / coils / spark plugs are a bit difficult to get to.

An easy way to check the coils is just to swap a good one for a bad one in vivo and listening to the engine or disconnecting the coil in question in vivo. A youtube video mechanic suggested it is easier and most cost reasonable to change the plugs / coils at shorter intervals rather than waiting for issues which can lead to more costly fixes. IE: instead of waiting to change oil (well synthetic nowadays) at 10k or more miles changing the interval to 10 k miles or once a year.
