Why Is My Car Losing Power with the Check Engine Light On?
What the customer reported
The vehicle owner noticed the check engine light was illuminated and experienced reduced power while driving.
What we found and did
The technician conducted a diagnostic inspection and identified issues related to the vehicle's timing chain and coolant system. The team at our Lake Wales shop performed a timing chain replacement and conducted a complete coolant system flush. They used a BG machine to withdraw old fluids and refresh the system with new coolant, ensuring optimal engine performance.
Result
After the repairs, the vehicle ran smoothly, and the check engine light was no longer illuminated.
Pro tip
If your check engine light comes on and power is reduced, it could indicate a timing chain issue. Addressing it promptly can prevent more severe engine damage and keep repair costs lower.
