Why is my check engine light on?

A check engine light indicates that the vehicle's engine computer has detected a fault in the engine. This warning can come on for many different reasons, from misfires from mechanical failures to a loose gas cap. Properly testing with the latest equipment with a trained technician is the best course of action. Reading a code from a code reader is only a clue as to where to look for the problem, testing needs to be performed to verify which component has failed. Here is an example: you have a code P0456 which is a small leak in a vehicle's EVAP system. This code could be set for so many different reasons; it could be a bad purge valve, vent valve, fuel tank pressure sensor, a leak in a hose from the engine to the fuel tank, a bad gas cap, a bad hose to the fuel fill port, among other things. Replacing parts one by one would be very inefficient and time-consuming. This is where proper diagnosis will save money and time.

Why is my vehicle sputtering?

Sputtering is usually caused by a misfire in the engine. This symptom will often cause the vehicle to shake, lack power, and vibrate excessively. It is often accompanied by a flashing or solid check engine light. Sputtering can do damage to your vehicle's catalytic converter and will make the vehicle run inefficiently. We recommend bringing in a vehicle that is sputtering immediately to have our experts check it out.

Diagnosing your vehicle's clunking sound

Noises while driving including clunking and thudding can depend on the situation that they occur in. If your vehicle clunks over a bump, it is likely a failed suspension component like a strut, strut mount, or shock absorber. If the vehicle clunks when applying the brakes, it could be a loose or broken control arm bushing or a loose brake pad. If the vehicle is clunking when accelerating, think of motor mounts.
