hey just had the car tuned up and the check gague came on doesnt stay on but the rpm is now at 600 in stead of 750

but when i put the car in drive that its normal idle

what can anyone tell me about this.
 
The check gauge light will only come on if you are extremely low on fuel, no oil pressure, or the temp gauge is close to the hot side.
 
the oil pressure seems to be ok and i do have a full tank of gas and the temp seems to be in the normal range....


I'm just really curious why all of a sudden it happened
