Engine Performance problem
1994 Ford Ranger 4 cyl Two Wheel Drive Automatic 200000 miles

My truck is really rough idle when it is cold sometimes it even dies while idling. Once it warms up it does good. Also check engine light is on and we have it tested and it shows O2 sensor and we have replaced all of them and it is still on. What else could it be? We test it and it still says O2 sensor. Thanks for any help.

Rough idle try cleaning out the idle air control valve and see what happens and for the O2 sensor lite could be the wiring or the computer itself
