A high idle in your 1996 Pontiac Firebird with a 3.8-liter engine can be caused by several factors. Common issues include a vacuum leak, a malfunctioning idle air control (IAC) valve, or a dirty throttle body. Additionally, problems with the engine's sensors, such as the throttle position sensor (TPS), can also lead to an elevated idle. It's advisable to diagnose these components to pinpoint the exact cause.
