Check Engine Lights
Don't ignore it — advanced diagnostics pinpoint the issue fast, so you're back on the road with clarity and confidence.
A check engine light means a stored fault code, but the code alone doesn't name the failed part — a misfire code, for example, could point to a coil, plug, injector, vacuum leak, or compression problem, and diagnosis is the testing that narrows those possibilities to one. Replacing parts based on the code alone is a guess, not a repair.
The one distinction worth knowing: a steady light usually means it's safe to drive to a shop, while a flashing light indicates an active misfire that can destroy a catalytic converter within minutes and needs immediate attention. Impact Auto Repair uses dealer-level scan tools to get to the actual cause, with a plain-English explanation of what was found before any repair is recommended.

Check Engine Lights — Questions
Yes — a flashing light usually indicates an active misfire that can damage the catalytic converter. Reduce load and have it checked promptly.
A steady light usually means you can drive to a shop, but it shouldn't be ignored — many faults quietly increase fuel consumption or emissions. A flashing check engine light is different: it indicates a severe misfire that can destroy the catalytic converter within minutes. If it's flashing, reduce speed, avoid heavy throttle, and get the vehicle looked at immediately.
Sometimes, if the condition that set it doesn't recur across several drive cycles. The stored code generally remains in memory, which is useful — the light going out doesn't mean the fault was resolved.
