• Secondary Air Injection System Failure
  • Description/Symptoms: The secondary air injection system helps reduce emissions during cold starts. Components like the air injection pump and valves can fail, triggering the check engine light and potentially causing the vehicle to fail emissions tests.
  • Solution: Replacing the faulty components, such as the air injection pump or valves. Some owners choose to bypass the system, though this is not legal in all areas.
  • Estimated Cost to Fix: $500 - $1500+
• Exhaust Manifold Cracking/Leaking
  • Description/Symptoms: Cracks can develop in the exhaust manifolds, leading to exhaust leaks. This results in a louder exhaust note, reduced engine performance, and potential for exhaust fumes to enter the cabin.
  • Solution: Replacing the cracked exhaust manifold.
  • Estimated Cost to Fix: $500 - $1200+
• Valve Cover Gasket Leaks
  • Description/Symptoms: Oil leaks around the valve covers. The smell of burning oil may be present.
