Can a Bad Oxygen Sensor Be the Cause of Black Smoke Coming From the Tailpipe

Oxygen sensors are used in modern vehicles to provide engine control module (ECM) information about the gases coming out of the combustion chamber, as well as the catalytic converters. When the oxygen sensor goes bad, ECM gets incorrect information and cannot properly adjust air-fuel mixture going into the combustion chamber. As a result, you may notice following symptoms: Check engine light comes “on” Engine accelerating in spurts Reduction in gas mileage And yes, black smoke coming out of the tail pipe due to excess fuel entering the combustion chamber. So if you see black smoke coming out of the tail pipe of your vehicle, there is a good chance that an oxygen sensor is the culprit. It is important to get this condition repaired, before excess carbon in the exhaust causes catalytic converter problems. Call Adams Autoworx to make an appointment, or make an appointment on our website. Your vehicle will need professional help to get back in top shape.

Why It Is Important to Inspect Engine Mounts

Adams Autoworx in Castro Valley offers comprehensive automotive maintenance, factory recommended services, diagnostics and repairs. As we write this blog post, various surveys reveal that more and more vehicle owners are keeping their vehicles longer. As vehicles age, more and more parts can fail, and so everybody should be cognizant of the need to inspect engine mounts. As your vehicle ages, engine mounts can break. Usually it starts with just one, but then the remaining mounts are forced to work harder, and deal with greater range of motion because the engine is no longer fully secured to the body of the vehicle. As a result, more engine mounts can fail. Engine mounts not only keep the engine attached to the body of the car, they are also tasked with minimizing vibrations. When an engine mount fails, you may feel increased vibration and increased noise. As more engine mounts fail, these symptoms will become even more pronounced including unusual noises such as rattling or clunking ... read more

2011 Subaru Forester: Excessive Oil Consumption and Oil Leaks

We are big fans of Subaru vehicles, but they occasionally come with an issue or two. The 2011 Subaru Forester has two engine oil issues that owners need to be aware of:   first and foremost, the engine can consume too much engine oil while operating, the other issue is oil leaks. Excessive oil consumption is a known problem for a number of vehicles, and unfortunately, 2011 Forester is one of them. It can be 1 - 2 quarts between oil changes, but sometimes as many as 3-4 quarts. If you own a 2011 Subaru Forester, we highly recommend checking engine oil levels every 1000 miles and topping it off if necessary. This will keep your vehicle from depleting the engine oil. Oil leaks are always a concern, and unfortunately older Subaru vehicles are oil leak prone. An oil leak can be particularly dangerous if your Subaru also has a tendency to excessive oil consumption. If the two are combined, and the owner does not monitor engine oil level, the vehicle may run out of engine oil &nda ... read more
