94 ex rough idle please helpp



#1
Ok I have a 1994 Civic Ex with stock D16z6 automatic I just bought and im having problems with idle. When its sitting at a red light or in park it idles really rough with a kinda miss to it and veryy sluggish take offs but after you get it up to speed at over 2500 rpms it does fine and clears out. It has a new: Diz cap and button, plugs gapped right and new wires, fuel filter. car is bone stock to. Also its throwing code for front O2 sensor but i wasnt sure if it could make it run so rough. Anyone that can help I would really appriecate it.

A bad primary O2 sensor will make your car run like crap. Change it anyways.

After that if it still idles rough, try adjusting the idle.
