Check Engine & Diagnostics in Rochester.
B & B Automotive diagnoses check-engine lights and driveability problems in Rochester — the real cause, not a parts-swap guess.
Call (585) 342-3800A check-engine light is a symptom, not a diagnosis. The code a parts store reads off your car names a circuit, not a failed part — and replacing the part the code mentions is how people spend four hundred dollars and still have the light on. A misfire code can be a coil, a plug, an injector, or a vacuum leak feeding one cylinder.
Diagnosis here means pulling the codes, then testing the actual system: live data, fuel trims, and where the readings drift from what the engine should be doing. You get told what failed, what it costs to fix, and what happens if you leave it — before anyone touches a wrench.
Describe what the car is doing — the noise, when it happens, what changed. Half the diagnosis is in the description.
What actually failed, what it costs to fix, and what happens if you wait — before any work starts, not after.
The repair gets done and you get told why it failed, so you know whether to expect it again on this car.
★★★★★“I'm already loving this place! They're fast, sufficient and very nice friendly hard workers! Brian especially is a great person! I like how they all get straight to the point!”
★★★★★“Got a tire pressure warning at 4am just right before my trip back home. My trip got delayed and tried to find a place that opens early and able to fix my flat. I am glad I found this place because they were welcoming and willing to help.”
