Your idle should be controlled by the computer. Clean the throttle-body and idle air system. Check for applicable trouble codes. You should be able to check mil codes, yourself.

To check codes, you use a jumper wire between A & B terminals. Turn key just till the dash lites come on, no further. Then the mil on the dash starts flashing, you count the flashes to get the codes. Your looking for two digit codes.

Still having trouble with the idling of my car. The car runs smooth for about 15minutes then it sounds as if it wants to choke off. I've clean the throttle body and idle air system. I scanned it and have no trouble codes. What do I do now?

How long since a tune-up? Check for vacuum leak.

Does it run ok off idle? A vacuum leak would show up more at idle. Also, the 02 sensors are part of a tune-up. Can you put a scanner on it, that shows live engine data, see what the sensors are doing and whether or not the system is running rich or lean? I hate to see you throw parts at it.
