Mechanical Inspection: Compression
WARNING: This page is about a different car, the 1996 Mitsubishi Diamante, 1996 Mitsubishi 3000GT, and 1996 Dodge Stealth. However, it is still accessible from the selected car via links, so may be relevant.
Check engine mechanical condition with a compression gauge, vacuum gauge, or an engine analyzer. See engine analyzer manual for specific instructions.
WARNING:
DO NOT
use ignition switch during compression tests on fuel injected vehicles. Use a remote starter to crank engine. Fuel injectors on many models are triggered by ignition switch during cranking mode, which can create a fire hazard or contaminate the engine's oiling system.
