Hey Scotty, I have a 2002 Lexus ES300 with 174,000 miles. My check engine light flashed while I was driving and I took it to the dealer to have the spark plugs changed. It runs better at idle but it still flashes while I’m driving. I also got the code PO331 from the dealer. What could cause the check engine light to keep flashing? Thanks for your videos on YouTube.

Google search the code. It will tell you what it means and what causes it.
(it's a misfire)
