Welcome to this forum! I've renamed your thread, and moved it into the stock 95-01 section.

sounds like your intake gaskets or a vacuum leak somewhere. is your check engine light on?

 

[BurnTheLight88]

Ditto. My '99 work explorer did the exact same thing, it was vacuum leak.

SOHC? You probably need intake gaskets.

engine temperature sensor?

Do you have any diagnostic trouble codes?

You could have a bad engine temperature sensor that sends the data to the PCM. If the PCM doesn't know that the engine is cold it doesn't richen the fuel mixture accordingly.

Yeah, I would check the sensors and vacuum leak first as that should be fairly easy. Clean your IAC and MAF while you're at it if you haven't before.
