My 2001gls is idling poorly(if at all). The vehicle is under 60k miles and very clean , Had new plugs installed a month or so ago and it remedied the problem for a bit of time but not long.Wondering if it may bee a consistent sensor or electronic element failure or....? I can nbot drive it to a code reader presently . I apreciate all input .
Thank you ,

1. Make sure the rubber air intake boot between the throttle body and air flow sensor is properly attached and not cracked.
2. Visually inspect the engine vacuum lines. Listen for hissing sound indicating a possible vacuum leak.
