Logs after NGK One-Step Colder .018 Plugs. Still same coils and no other changes. 9-9-2021 Changed Spark plugs to NGK IR one step colder gapped to .018. **At first it was misfiring at idle, might have been a loose coil connector. After that I drove the car very slow around the block and it seemed fine. Then gradually drove it quicker around the neighborhood and eventually doing some pulls/logs. Misfires went away and car felt really good.
