94 4 runner cold start problem

I have a 94 4 runner 4wd v6. I am having problem keeping the idle in normal rpm when the engine is cold. It will start but rpm will drop fast and die if I don't put gas to keep the engine running. However, it will run fine after the engine warm up. Anybody experience same issue or know what is going on?:banghead:

Welcome to the AF!

Check your cold start injector/injector time switch, and your ECT sensor.

Try cleaning your throttle body:

Just cleaned the throttle body but it still acts the same... developing skill to test the rest of the systems you have mentioned... thank you for the help and I'll keep you posted.
