I have had my Manual CX-5 for about a week and a half now and normally when I start the engine my tac shows about 1500 RPM for about 10-15 seconds then idles down to about 500 RPM. The other day after I started the engine went to the normal 1500 RPM then 3 seconds later jumped to 3000 for about 5 seconds. I have never had this happen again and have no clue why it happened? Someone was just getting in the passenger seat at the time so I don't know if the sensor in the seat triggered the air bag on and drew more power so the engine revved to compensate? Just curious if anyone else has noticed this on the manual CX-5 or when you should worry about it (obviously it only happened once) This is my first new car ever so I have no clue what to expect from a vehicle.
