Rav4 P0300 code. Counterfeit spark plugs.
I had a P0300 code for random cylinders’ misfire for a couple weeks now. Today I went to check the spark plugs and all six plugs’ electrode had worn down badly. They were on the car for a little less than 40,000 miles. They are supposedly Denso Iridium in Toyota packaging from EBAY.

The original language was likely Japanese, so whichever/whoever translator they used didn't understand the proper spelling and grammar. How often do I use "malpractice" in my everyday speech (not a lawyer)?
