Is it normal for a 99 SS to idle at 500 rpm, my car before this was a 98 V6 Camaro which idled at 900.

Mine idles at 600 but then again sometimes our tachs are off. If it isn't stumbling don't worry about it.

mine is 600

 

Mine idles around 650-700. If it sounds fine it probably is. Autotap will tell you the actual idle speed.

Mine idled at 900 until I changed plugs/wires and now it idles at about 600.I don't think you have anything to worry about.

Was it idling at 900rpm with the A/C on? I’m having the same problem with my 2015 camaro, about a week ago I was parked and I notice a shift in the idle speed . Mines now idles at 900rpm with the A/C and when it’s off it’s back to 500rpm. Should I also replace my spark plugs/wires. Or is it something else. My car is at 80k

 

You're in the 4th Gen (up to 2002) engine section. You need to post in 5th Gen Tech. Unfortunately, not many 5th Gen members on this site.

You also need to indicate the specific engine and trans in your Camaro. Idle RPM is different for manual and automatic transmissions.
