low idle when slowing down to idle
Not all the time but sometimes when i stop or slowdown almost to a stop it will idle down to about 200-400rpms. So far ive cleaned the MAF, IAC, and throttle body. i bought a new IAC to see if it was bad but no change still does it. Also sometimes when im stopped at a redlight it feels like it bucks a little. and if i pull off the pcv how would i diagnose if its good or bad? what else should be checked for this idle problem? thanks for all help in advance

you could check it though if it rattles it's good.
before doing anything i would reset the computer and see if the problem goes away after the engine learns new fuel air trim.

what i do after a reset is let the engine idle turn on all accessories high beams fan etc, turn the wheel lock to lock a few times then shut all power stuff off and let it idle again for 5 minutes then drive.
