FAQs

Repair or replace my engine?

We’ll compare targeted repair, a low-mileage used engine, or a rebuild based on mileage, condition, and value—with transparent pricing.

Can I keep driving with the Check Engine Light on?

If it’s flashing, stop and call us. A steady light indicates a stored fault—diagnose soon to avoid collateral damage.
