Gasoline Engine Repair and Maintenance

Combustion (Gas) Engine Repair & Maintenance

From routine maintenance to major engine replacement or repair, we know engines better than anyone.

The Engine is the single most important component of your vehicle and keeping up with recommended Engine maintenance and handling repairs right away will help your engine last the life of the vehicle. Regular Tune-Ups, Filter Replacement, and Fuel System Cleanings help to keep the Engine running smoothly.

Engine Repair problems can be extremely complex, especially in the newest luxury models - and require a highly skilled technicians with state-of-the-art equipment and knowledge to identify the root issue with your vehicle. Issues with drivability, lowered fuel economy, and your Check Engine Light are all indications that your engine needs to be serviced.

There are basic maintenance items such as regular oil changes, spark plug replacement, and changing clogged filters can extend the life of your engine and increase reliability. A list of suggested Tune-Up Services is available here. Some wear and tear on the engine is inevitable.

Regular Engine Tune-Ups can prevent costly damage.

It's recommended to regularly inspect your engine for performance and issues. Have new spark plugs installed when called for by your owner's manual or technician, and have the timing and idle set with this service. Have your Air Filter and Fuel Filter changed regularly, especially if they become clogged with debris. Having your Fuel System cleaned can also improve engine performance and extend the life of your engine.

Sometimes, engines have already experiences some part failure due to damage or wear-and-tear and need more than a simple Tune-Up Service. Some key engine components such as the Fuel Pump, Ignition Wires and Module, Engine Sensors and Distributor Cap & Rotors often need to be repaired or replaced over time.


When we rebuild your engine, we also install a brand new gasket set and new timing belt to ensure performance. All rebuild engines require a core exchange.


Vehicles require a proper mixture of air and fuel in the engine in order to combust properly and for the vehicle to run smoothly. The amount of air introduced is controlled by the air intake system.

Mass Air Flow (MAF) Sensors measure the amount of airflow entering the Air Intake Manifold and must be able to communicate clearly with the Engine Control Module (ECM). The OEM Mass Air Flow Sensor offered by Clackamas Tire & Brake are guaranteed to ensure accurate airflow, precise performance, and longer service. MAF Sensor performance is largely determined by highly precise calibration.

Choked Air Flow Calibration ensures precise mass airflow output that exactly matches OEM specifications for your vehicle, with superior corrosion resistance and superior joint strength for added durability. By precisely matching your OE output, we guarantee your MAF Sensor performs flawlessly under all operating conditions, for over 90% of all available makes and models.

The Mass Air Flow Sensor measures the temperature and volume of air flowing into the engine through the air intake manifold. This is used to adjust the fuel mixture and create efficient combustion in the cylinders. If your MAF goes bad, you will see a loss in engine power and the CEL light may come on. This can be easily diagnosed by reading the error code with a diagnostic computer.

The throttle body is a butterfly valve (often made of aluminum) that exists within the air intake system, located between the Air Intake Filter and the Air Intake Manifold. The duty of the throttle body is controlling the amount of air flowing into the engine in response to the pressure applied to the gas pedal, via the link of a flexible cable that moves the throttle shaft when the gas pedal is depressed the person operating the vehicle. As air enters the engine, the throttle body injects more fuel and allows for more power.

Electronic throttle bodies have a very high failure rate, negatively impacting a vehicle's power, gas mileage, and drivability. Stalling, rough idle, poor acceleration, faulty Check Engine Light codes, and poor fuel economy are all symptoms of a dirty throttle body. Poor gas mileage happens when the vehicle's ECU attempts to adjust the fuel mixture to compensate for the throttle plates that are unable to close properly. We replace your failed throttle body with a new direct-replacement unit to ensure maximum performance and reliability, available for an array of domestic and import vehicles, including but not limited to Audi, BMW, Ford, GM, Toyota, and Volkswagen.

Throttle Position Sensors: As the throttle moves, a mechanical arm with in the sensor makes contacts with different points on a resistor strip, a connection that creates a voltage signal for the Powertrain Control Module (PCM). When a Throttle Position Sensor is misaligned it will produce a poor idle, lack of power, inproper transmission shifting, and engine stalling. On certain Honda and Acura models, the TPS cannot be serviced separately and the entire throttle body assembly must be replaced.
