Engine Shudder At Idle Sounds Like Its About To Die. It came back as the tps. Have recently noticed this in my ride during idling.
As the situation becomes worse, it can also cause the vehicle to stall.
So i checked these forums and decided i would change the iac. As the situation becomes worse, it can also cause the vehicle to stall. These are the components that you should check first car shakes when idle. Egr sticking open, ask your shop to check your egr valve operation.

If the clutch is dragging or not fully disengaging, perhaps due to a hydraulic leak or stretched cable, it induces a load on the engine. Whole proces takes about 10 seconds or so.

You may have a problem with idle speed control motor or etc as gm calles it.
If the tube has a crack in it somewhere, it will run rough and when you take off, your engine will hesitate or stall. Sounds like a vacuum leak. Low fuel pressure will cause the engine to run very leanly, and therefore it may cause the engine to sputter. This is most often felt at low speeds and can lead to vehicle stalling.
Misfires , make sure ignition system is in good repair and all ignition related service up to date. When i'm idling at a light, the rpms drop to like 500 and it starts to chug a bit as if its gonna die, then i guess the iac opens up an the rpms shoot up to 1100, then it slowly falls back to 500 rpm and repeats. It came back as the tps. Low fuel pressure will cause the engine to run very leanly, and therefore it may cause the engine to sputter.
