Engine Tune-up

Fuel Injection Service

When your car idles rough, hesitates, stalls, or it does not seem to have the power or fuel economy it once had, a Fuel Injection Service may be the answer. Often these symptoms are mistaken as signs that a tune up is needed. As you drive your car, carbon deposits build up on fuel injectors, engine valves and in the combustion chambers. Deposits also form on the throttle body, and in the intake manifold as well as in the catalytic converter. This accumulation of carbon and sludge can cause a drastic drop in both fuel economy and performance. Fuel additives are largely ineffective because they target only the fuel injectors and are not concentrated enough to clean away stubborn carbon build up. They do nothing to address the other areas that are arguably more important than the fuel injectors. The only proven way to clean the entire fuel and intake systems, as well as the combustion chambers, engine valves, and catalytic converter is by performing a comprehensive Fuel Injection Service. For this service to be effective, it must be performed by a qualified technician using the proper equipment and solvent solution. It is recommended that this service be performed every 2 years or 25,000 miles as part of your routine maintenance schedule to keep your car running clean and efficiently, and performing like it did when it was new.

Fuel System Warning Signs:

  • Your vehicle is hesitating.
  • Your vehicle is having trouble starting.
  • Your vehicle is achieving poor gas mileage.
  • Your vehicle is operating sluggish with poor performance.
