Without being there to physically inspect your 1996 Toyota, it's very hard to pinpoint the exact issue. However, you might want to have the idle air control valve inspected.
One of the most common symptoms commonly associated with a problematic idle air control valve is irregular idle speed. The idle air control valve is programmed to regulate and maintain the engine idle speed at a controlled rate.
