I bought this car with 50,000 miles on it and I noticed that idle it would bounce stumble almost sounds like a misfire 90% of the time it says PO 500 misfire on cylinder five every now and then it will do a random misfire PO 300. I did a head gasket test with the combustion liquid that you put in the radiator and it’s coming back negative change the coils and swapped fuel injectors from five to another one nothing changed I think the only thing left is maybe something in the valve train? Is anybody else having this problem because what’s throwing me for a loop is it’s weird to think of valve would go out at 50,000 miles.
Po500, and po300
