I have a 98 accord v6 that will jump idle between 1k and 2.2k rpm. When driving this is not too much of an issue until the transmission down shifts then the engine tries to catch up. Getting multiple cylinder misfires and air idle control.
The codes I am getting are:
505 code and cylinder misfire code, I don't have the number. I did reset the codes and now only the 505 code comes up at the moment.
It was running fine the other day and then just today this happened.
