The vehicle starts and runs good while cold. Then after warming up it loads up.

We replaced all emission parts.
Replaced control module.

This had no effect.

Have you replaced the O2 sensors? Have you checked to see if the catylatic converter is plugging? I can't remember if the 88 had throttle body injection or a carb. I memory serves me right, it's TBI. If so, when the engine is loading up, check to make sure the tbi is spraying a fine cone shaped mist of gas to the engine and not dripping. If carb, make sure the choke flap is opening properly.

Let me know what you find.
