NKG Auto Repair - Bayview, San Francisco
Check Engine Light and Engine Diagnostics in San Francisco
A check engine light can mean anything from a loose gas cap to a problem that needs attention right away. Reading the code is the first step. Finding the actual cause is the real job.
We scan your vehicle’s computer, test the systems involved, and explain what’s wrong in plain language. You get a clear estimate before any repair, so you’re not paying for guesswork.
When to bring it in
- The check engine light is on or flashing
- Rough idle, misfires, or hesitation when you accelerate
- Hard starting or stalling
- Worse gas mileage than usual
- New noises, smells, or smoke
What we do
$$

- Testing to confirm the cause instead of guessing at parts

Final cost depends on your vehicle, parts, and labor. You’ll get an estimate before any work begins.
Common questions
Is a flashing check engine light worse than a steady one?
Usually, yes. A flashing light often means an active misfire, which can damage the catalytic converter. Avoid hard driving and get it checked soon.
Can’t I just get the code read at an auto parts store?
A code tells you which system reported a problem, not always which part failed. Diagnosis means testing to confirm the cause, so you only pay for the repair you actually need.
