What causes intermittent power loss in a 2015 Chevrolet Corvette Z06 under hard acceleration?

 
Potential Causes of Intermittent Power Loss
 

Fuel Delivery Issues
 

• Fuel Pump: A malfunctioning fuel pump that cannot maintain consistent pressure during high demand can cause intermittent power loss. The straining pump fails to provide the engine with enough fuel under hard acceleration.
• Fuel Filter: A clogged fuel filter restricts the flow of fuel to the engine, leading to a temporary loss of power when more fuel is needed.
• Fuel Injectors: If the fuel injectors are dirty or faulty, they may not deliver the correct amount of fuel to the combustion chamber, especially under heavy acceleration.

 
Air Intake Issues
 

• Air Filter: A dirty or clogged air filter can prevent sufficient air from reaching the engine, causing a drop in performance under hard acceleration.
• Mass Air Flow (MAF) Sensor: A faulty MAF sensor can send incorrect air flow data to the engine control unit (ECU), leading to improper air-fuel mixture and intermittent power loss.

 
Ignition System Problems
 

• Spark Plugs: Worn or fouled spark plugs can cause misfires, which are particularly noticeable during hard acceleration.
• Ignition Coils: Faulty ignition coils can lead to intermittent firing of the spark plugs, also resulting in power loss.

 
Throttle Body Issues
 

• Throttle Position Sensor (TPS): A malfunctioning TPS can cause erratic throttle response, leading to inconsistent power delivery.
• Dirty Throttle Body: Carbon build-up within the throttle body can disrupt airflow and cause intermittent power loss.

 
Transmission Concerns
 

• Transmission Slippage: If the transmission slips under load, it can create a sensation of power loss during hard acceleration.
• Transmission Control Module (TCM): Issues with the TCM can result in improper gear selection or delays in shifting, affecting acceleration.

 
Engine Management System
 

• ECU or PCM: A glitch in the ECU/PCM can lead to erroneous data processing, adversely affecting the engine’s performance.
• Sensor Issues: Various sensor issues, like a faulty oxygen sensor, can send incorrect data to the ECU, causing erratic power delivery.

 
Additional Factors
 

• Heat Soak: Extended periods of hard driving can lead to heat soak in components like the supercharger, causing temporary power loss due to high intake air temperatures.
• Traction Control System: The car’s traction control system may limit power to prevent wheel spin, which can be incorrectly perceived as power loss.

 
Conclusion
 

Intermittent power loss in a 2015 Chevrolet Corvette Z06 under hard acceleration can be attributed to a variety of issues involving fuel delivery, air intake, ignition, throttle body, or the engine management system. Each potential problem should be systematically diagnosed and addressed to restore full performance. Consulting a professional mechanic experienced with Chevrolet Corvettes is recommended for accurate troubleshooting and resolution.
