since i got autostart i let my car warm up 10-15 mins before i take off in the morning is that bad for the car? and after work i start it and it sometimes idles for 15-20 mins before i leave. is this okay for my car ?

 

no, that won't hurt your car. not unless you leave it in gear when you remote start it .

 

It's okay for the car, but not the environment. And your back pocket.
