What is the 1994-2001 Acura Integra Timing belt failure on interference B18 engine bends valves?
All B18 engines in the 1994-2001 Integra (DC2/DB7) are interference-design. If the timing belt snaps (or jumps teeth from a seized tensioner or water pump), pistons strike open valves. The belt should be replaced every 90,000 miles along with the water pump, tensioner, and seals. Repairs typically run $350-$3,000. Severity: high.
What is the 1994-1999 Acura Integra Internal distributor failure causing stalling, no-start, and misfires?
The TEC/Hitachi internal-coil distributor on third-generation Integras is a chronic failure point. Heat from the internal ignition coil degrades the coil, igniter (ICM), and bearings, causing intermittent stalling at operating temperature, hot-restart problems, and dead no-starts… Repairs typically run $250-$600. Severity: high.
What is the 1994-1999 Acura Integra Ignition switch contact pitting causes engine to die when key released?
