FAQ
Engine Diagnostics & Repair — FAQ
My engine is running rough — what could it be?
A rough-running engine is often caused by worn spark plugs, ignition coils, a vacuum leak, dirty fuel injectors, or a failing sensor. We'll diagnose the exact cause rather than guessing, so you only pay to fix what's actually wrong.
Is it worth repairing an older engine?
Sometimes yes, sometimes no — and we'll give you an honest answer. We weigh the repair cost against your vehicle's value and condition so you can make the smart decision. We won't push a big repair on a car that isn't worth it.
Do you do transmission rebuilds too?
We don't perform transmission rebuilds in-house, but we're happy to recommend a trusted local specialist. We can still handle transmission fluid and filter service — see our transmission service page.
