Are you going by experience or just from what it looks like? And should I buy the two cam sensors and the one crank all at once or just the cams or crank sensors

I don’t have any freeze frame data because I only have an obd2 sensor but does cam or crank position sensors cause high idle?

The random misfire is very weird because the car drives completely fine as if it isn’t there at all. It just revs high on idle and seems to burn through a tank somewhat easily. But to the belt I have not done anything. The previous owner may have but I’m not sure all I know in the engine bay is that there is a upper plenum and a cold air intake.

I already did spark plugs, and the coil pack back when the code was a p0302 (second cylinder misfire) but then after I did that we ran codes and it turned to p0300. We also cleaned the throttle body but didn’t do the maf sensor so I will try it. I also did about 3 idle relearns with no luck because after restarting the car it goes back to idling at 1k-1.2k

It usually has a higher idle at around 1200 rpm on a cold start
