Not every misfire is an ignition problem.

Clogged, leaking, worn, or electrically weak fuel injectors can cause rough idle, hesitation, uneven cylinder fueling, poor throttle response, and misfire symptoms that are often blamed on spark plugs or ignition coils. Professional injector testing helps determine whether the fuel system is actually contributing to the problem before more parts are replaced unnecessarily.

Injector Service Packages

Every package includes the same complete cleaning and testing process.

Pricing shown below applies to standard top-feed port fuel injectors only. GDI injectors are serviced under separate GDI service packages. Side-feed and unusual injector types require approval before ordering. Diesel injectors are not currently serviced.
Simple, transparent pricing with no hidden fees. What you see is what you pay — standard U.S. return shipping included.
