About This Service
A modern tune-up focuses on the parts that wear: spark plugs, ignition coils, air filters, and sometimes fuel system cleaning. Spark plugs have long service intervals now, but they still wear out — and when they do, they put extra strain on the ignition coils.
Misfires are one of the most common reasons for a flashing check engine light. We identify which cylinder is misfiring and test whether the cause is the plug, the coil, the injector, or something mechanical, so you only replace what's needed.
We use the correct plug type and gap for your engine and quality ignition coils. On many European and turbocharged engines, the right plug is especially important for performance and reliability.
Replacing worn plugs and coils restores smooth power, can improve fuel economy, and protects the catalytic converter from damage caused by unburned fuel.

Frequently Asked Questions
Common questions about tune-ups, spark plugs & ignition coils in North Richland Hills and nearby cities.
How often should spark plugs be replaced?+
It varies widely — some engines call for plugs every 30,000 miles and others go 100,000. Turbocharged and high-performance engines often need them sooner. Check your owner's manual or ask us.
What causes an engine misfire?+
Common causes are worn spark plugs, failed ignition coils, clogged fuel injectors, and vacuum leaks. Less commonly, it's a mechanical issue. We test to pinpoint the cause.
Should I replace all the ignition coils at once?+
Not always. If one coil fails on a high-mileage engine, others may be close behind, and replacing them together can save labor. We'll give you both options.
Is it safe to drive with a misfire?+
A misfire can damage your catalytic converter, which is expensive to replace. If your check engine light is flashing, reduce speed and have the car checked soon.
