Bad idle when warm!

Bad idle when warm!
My 1995 4runner 3.0 runs really rough when i start it up after it is already warm. Runs fine when its a cold start, but when it is started when warm, the idle starts to drop until it dies. When i try to start it again, and i give it some gas to keep the rpms up, it jsut shakes and doesnt really do anything, even if i floor it! And if i can get the car moving by revving it and trying to drive off, it runs like crap for a few miles, then goes back to normal. I really cant figure this out, i have changed the throttle position sensor, fuel filter, i have checked all the plugs, and intake, and now im stuck! please help!

no it doesnt happen when its 20 below outside, it only happens when my engine is warm...
I think it might have to do with the fuel pump, but im not sure, i might just go for it and see what happens...

I've had the same symptoms on my 3VZE and changing the O2 sensor helped significantly. It sometimes hiccups after a warm restart, but no longer stalls out like it used to before the O2 swap.
Here's a thread that you may want to look at:

Good Luck!

thanks troy. i swapped out the 02 sensor and it fixed my issues. I no longer have the high idle and it doesn't sputter anymore. PLUS, my gas mileage is exceptionally better.

Mine has two O2 sensors I think. Which one did you replace? Did you replace both? One more symptom to report - when it is idling really low like that, my exhaust smells horrible
