Engine & Electrical Diagnostics
Noises, warning lights, and intermittent faults get diagnosed properly before anything gets replaced. We test, narrow it down, and then quote. Pricing depends on where the fault is and how hard it is to reach, and you hear that number before the wrench comes out.
It pays off. A customer chasing a loud whine on acceleration had researched their way to vacuum leaks, cracked seals, and manifold gaskets: expensive territory. After several tests it turned out to be two very loose bolts. They drove away with the car running smoother than before and paid nothing but the diagnostic.
That's the whole point of diagnosing first. The cheap fix only shows up if somebody actually looks for it.
