the car will try to start but will not idle unless you give it gas

the light is on yes and how do u go about cleaning the throttle body

Well i stated try having it cleaned but you can check out youtube for a how to video... then look to see if you can find a video for getting trouble codes also. Seeing it done is much better than reading about it being done!! .. I dont type that well...or that much!!

is there anything else u can think that it may be?
