2006 Lincoln LS
The 2006 Lincoln LS is a mid-size luxury sedan known for its blend of comfort and sporty handling. It came with two engine options: a 3.0L DOHC V6 producing 232 horsepower and 220 lb-ft of torque, and a 3.9L DOHC V8 delivering 280 horsepower and 286 lb-ft of torque. Both engines were paired with a 5-speed automatic transmission. Owners generally appreciate the LS for its smooth ride, comfortable interior, and distinctive styling. However, common complaints revolve around reliability issues, particularly with electrical components and some engine components.
Engine
3.0L DOHC V6
- Coil Pack Failure
- Description/Symptoms: Misfires, rough idling, decreased fuel economy, and a check engine light. The engine may shake or run poorly.
- Solution: Replace the faulty coil pack(s). It is often recommended to replace all coil packs at the same time to prevent future failures.
- Estimated Cost to Fix: $80 - $200+ per coil pack, depending on labor and part quality.
- Recalls: None Found
- Variable Intake Manifold Runner Control (IMRC) Issues
- Description/Symptoms: Reduced engine power, especially at higher RPMs. A check engine light may illuminate with codes related to the IMRC system.
- Solution: Replace the IMRC valve or solenoid, or repair any vacuum leaks associated with the system.
