FAQs
Is it better to repair or replace my engine?
It depends on mileage, maintenance history, and vehicle value. We’ll compare targeted repair, low-mileage used engine, or rebuild options with a clear cost/benefit breakdown.
Can I drive with the Check Engine Light on?
If it’s flashing, stop driving and call us—continuing to drive can cause damage. A steady light means a stored fault—schedule diagnostics soon.
