Computerized Engine Analysis

Regardless of age, your engine should run like new.  Does your engine run rough?  Does it hesitates when you step on the gas? Is the Check Engine Light on?  Does the engine eat gasoline like it's free?  Is it hard to start when it's cold outside?  Does it cough, sputter, surge or runs unevenly?  Then you probably need a Computerized Engine Analysis to find out what's wrong.

Your modern vehicle's engine is a highly sophisticated piece of equipment. The days of your father's gas-guzzler are long gone—instead, Federal Exhaust Emission and Fuel Economy regulations demand that today's vehicles be equipped with electronic engine control systems to curb carbon emissions and increase fuel efficiency.

Tune-Up:

With technically-advanced control systems taking the place of simple engine components, common maintenance services such as TUNE-UPS ARE ALSO A THING OF THE PAST. Regular services (such as spark plug and filter replacements) are still required, as well as a computerized analysis of your vehicle's control computer. Our factory-trained technicians are here to provide these basic services.

Here's how your modern vehicle's control computer operates:

A network of sensors and switches monitor engine operating conditions and converts the information into electrical signals. The computer receives this information, and, based on information and instructions coded within this savvy computer program, commands are sent to three different systems: ignition, fuel, and emission control. Whenever a problem arises (as seen by that nagging "check engine" light), our service pros check whatever command is prompted, in addition to the status of your engine control computer and sensors. That way you'll know if your vehicle's performance is caused by a real problem, or just a sensor/computer issue.

Here's a partial list of your vehicle's sensory components:

• Air intake temperature sensor - measures the temperature of the air being inhaled by the engine. This information is used by the computer to adjust the amount of fuel delievered to the engine in cold weather.
• Barometric pressure sensor - measures the current barometer reading. The information is used by the computer to adjust the amount of fuel delievered to the engine based on the current barometer reading and altitude.
• Camshaft position sensor - reports the exact positon of the camshaft so the computer can determine the best moment for the fuel to be injected.  This maximizes fuel efficiency.
• Coolant temperature sensor - measures the temperature of the coolant.  This information is used by the computer to adjust the amount of fuel delivered to the engine to compensate for a cold engine.  This replaced the choke mechanism used on vehicles with an old-fashioned carburetor.
• Crankshaft position sensor - reports the exact postion of the crankshaft so the computer can adjust the exact moment to cause a spark to jump across the spark plug electrodes.  This ignites the fuel in the cylinder to produce power at the most efficient moment.
• EGR valve position sensor - measures how much the EGR valve is open.  The computer uses this to fine-tune the amount that the EGR valve is open and to determine if the valve is working correctly.
• Exhaust pressure sensor / transducer - measures the pressure of the exhaust in the exhaust system.  This information is used by the computer to help determine how much exhaust gas recirculation is required.
• Exhaust oxygen sensor - measures the amount of oxygen that has escaped the combustion process.  This information is used by the computer to adjust the amount of fuel being delivered to the engine and to monitor the effectiveness of the Catalytic Converter.
• Exhaust oxygen sensor - measures the amount of oxygen that has escaped the combustion process.  This information is used by the computer to adjust the amount of fuel being delivered to engine and to monitor the effectiveness of the Catalytic Converter.
• Knock sensor - listens for engine knock so the computer can reduce the igntion timing
• Manifold absolute pressure sensor - measures the amount of vacuum in the intake manifold.  The lower the vacuum, the harder the engine is working.  The computer uses this information to help determine how much fuel to deliver to the engine.
• Mass airflow sensor - measures the amount of air the engine is inhaling so the computer can deliver the right amount of gasoline.
• Throttle position sensor - measures how far you're pushing the accelerator pedal.  This information is used to determine how much demand the driver is placing on the engine and to determine how much gasoline to deliever to the engine for optimal performance.
