I am hoping someone here could point me in the right direction. I have a 93 4Runner with the 3.0 V6 motor that has a strange problem that is absolutely driving me bananas.

When the engine is cold, the motor starts right up. When the engine is warm/hot the motor just turns over and over and over and struggles to fire up - it acts almost as if the engine is "flooded", but with fuel-injection I didn't think this was possible - Someone at work mentioned vapor lock might be a possibility - Anyone have any ideas as to what is going on?

Thanks in advance.

Look at the info here. Sounds like the cold start injector is injecting whether it needs to or not.
