Why You Should Not Wait
A flashing check engine light means a misfire is actively damaging your catalytic converter — every minute you drive with it flashing is costing you money. Even a solid check engine light should not be ignored for more than a few days, as small issues can cascade into larger failures. Come in and know exactly what you're dealing with.
Frequently Asked Questions
Can I drive with my check engine light on?
If the light is solid, you can usually drive cautiously to our shop. If it's flashing, stop driving as soon as it's safe — a flashing light indicates a severe misfire that can destroy your catalytic converter quickly.
Does Kwik Kar fix the problem after the diagnostic?
Yes. Once we identify the issue, we provide a repair estimate and can perform many repairs on-site. If it's outside our scope, we'll tell you exactly what needs to be done.
Will the check engine light turn off on its own?
Sometimes, but the underlying issue that triggered it still exists. It's always better to have it properly diagnosed and resolved.
