2006 Pt cruiser idle problems

[Germando]

I have a 2006 PT with 40K miles. The car idles rough and runs sluggish at low speed. Problem will disappear with higher speed or by turning the AC off. The refrigerant levels are fine. The fan does spin at low speed at idle. What else could this be? Battery?


Thanks

Welcome to the forum.
Without knowing all the particulars, when was the last time the plugs and wires were changed. If they're stock from the factory, then it's a good possibility that's your problem. The OEM parts are cheap and don't last very long.

Aren't you still under warranty, or did you buy the PT used? Id used, then you probably don't know the history of your cruiser, so changing those parts would be a good idea anyway.
