I removed the JB4. They are pinning it on the
spark plugs "for starters", said they were incorrect. When asked to clarify what they meant by incorrect and they said not stock. They also noted the catch can and filters. They also said I have "
aftermarket wiring", despite having removed the JB4.
Their solution is to pay them to return it to stock. I passed. I took pictures of the plugs when I checked them. Maybe I need Hk rather than
Denso? I also still have the stock plugs set aside. I'm hoping I can resolve the misfire without having to return everything to stock. Any suggestions?
