Have a 2008 Acura TL 175k miles

Timing belt and water pump replaced Spark plugs replaced Cam shaft position sensor replaced Engine filter replaced Throttle body was cleaned Coils cleaned Spark plugs connectors also cleaned The electricity and compression was check and it was all good

After replacing the spark plugs and cleaning everything the Car is now idling at (800rpm) (1k) was the normal. idles up by itself as if I was accelerating -Misfire in a few cylinders

I’ve been to multiple mechanics and nobody has been able to find the reason for the check engine misfire light
