My '91 4Runner has problems staying running after it warms up. I don't know if its getting too hot, or bad O2 sensor. I flushed the radiator and replaced the sensor 'bout a month back and still have this problem. The truck starts fine, runs great down the road, but after driving for about 10 min. and I have to stop, it idles like crap. It's to the point that it is almost unsafe to drive in town, and it's my daily driver. HELP!!!

Not sure which engine you have but when my 22RE did this it was a combination of a bad AFM and TPS.

3.0 still needs fuel, spark and air to idle. Start there.
