Steady light: get it checked soon
A steady check engine light means the car’s computer has stored a fault code. The car is usually safe to drive for now, but the problem should be diagnosed soon. Small issues left alone can turn into bigger, more expensive repairs, and some faults hurt fuel economy.
Flashing light: reduce driving right away
A flashing check engine light usually means the engine is misfiring badly. Unburned fuel can overheat and damage the catalytic converter, which is an expensive part. Slow down, avoid hard acceleration and get the car checked as soon as possible.
If the light is flashing and the car shakes, loses power or smells hot, it is safer not to keep driving. Call for a tow: McCoy Towing is available 24/7 at (407) 305-0088.
Simple things to check first
- Is the gas cap tight? A loose or worn cap is a common cause of a steady light.
- Are other warning lights on, like oil pressure or temperature? Those need attention right away.
- Has anything changed: rough idle, hesitation, new noises, worse gas mileage?
Why reading the code is only the start
A code reader tells you which system reported a problem, not which part failed. For example, a misfire code can come from a spark plug, an ignition coil, a fuel injector, a vacuum leak or low compression. Replacing parts based on the code alone often means paying for parts you did not need.
A proper diagnosis tests the system the code points to and finds the actual cause. At McCoy Enterprises we explain what we found and give you an estimate before any repair begins.

This guide gives general information. Every vehicle is different: if something feels unsafe, stop driving and call for help.
