Hello,

Please check MAP.

A bad manifold absolute pressure (MAP) sensor can upset fuel delivery and ignition timing. Depending on your vehicle model, your engine might experience one or more of these performance problems:

• Rich air-fuel ratio
• Lean air-fuel ratio
• Surging
• Poor fuel economy
• It won't start
• Lack of engine power
• Stalling
• Detonation and misfire
