As your vehicle ages, its performance isn’t quite what it used to be, but many of us never notice the change because it’s gradual.  So here are a few questions to ask yourself.  Does your vehicle feel like it doesn’t have the pep that it used to? Have you noticed your fuel economy isn’t quite as good as it once was? Does it idle roughly or is it hard to start?  Do you hear the engine knocking? Has it recently failed an emissions test? All of those can be signs that your fuel and air induction systems are dirty and need cleaning.  Your fuel system takes gasoline from the tank to the engine’s combustion chambers where fuel injectors spray fuel that mixes with air and is ignited by spark plugs.  Black carbon deposits eventually can build up, obstructing fuel flow and diminishing your engine’s performance and fuel efficiency. The air induction system is what allows air to go into the engine’s combustion chamber.  Getti ... read more

Your vehicle gets its power from burning fuel, usually gasoline, and it counts on something called fuel injectors to send gas to the engine in a spray that is easy to ignite.  It’s a precise operation, and when it’s working well, you have plenty of power and an efficient engine. But after time, contaminants in the fuel system may prevent the injectors from spraying like they’re supposed to.  They can also shoot contaminants into the engine.  One sign that could point to dirty fuel injectors is a misfiring engine. Misfires can be caused by several things, so it’s a good idea to bring your vehicle to us so we can trace the cause. Another sign is that your fuel economy has gone downhill or your engine doesn’t have the “pep” it used to. If we discover that your injectors are clogged or not working the way they should, we can clean them to get rid of those contaminants to restore your engine to its top performance.  When you brin ... read more

Your vehicle has lots of doors including that one usually near the back on the vehicle's side.  That's the fuel door, something you use every time you gas up.  These endure hundreds of open-and-close cycles, usually without any problems.  But when they act up, it can be a major inconvenience for you. When they stick in the "open" position, it can present real dilemma.  You can still pump your gas, but do you just drive around with that flap sticking out the side? What happens if someone steals the gas cap or it gets damaged? What happens if it rains? Yep, it's decision time. A fuel door that sticks open can be due to a number of factors.  The hinge on the door may have broken, possibly from corrosion or it may have been hit sometime.  Some vehicles have a cable that operates the door and it could be loose.  The latch that holds the door shut could have broken or it, too, could be bent from something hitting it.  You probably want to take care of ... read more

A driver of a large SUV loaded with equipment was heading on a 7-hour work trip when he stopped at a gas station to refuel.  When he went to restart his SUV, it turned over but wouldn't catch.  Try as he might, he was never able to get it started again.  Of course there are many things that can cause those symptoms, but the next day he had his SUV towed to a service repair facility.  Using their test equipment, they were able to pinpoint the problem.  His fuel pump had failed.  The pump, which was located in the fuel tank, had to be replaced, and after awhile he was back on the road, delayed, but happy to be up and running again.  What had happened is that the pump was not strong enough to deliver adequate  fuel to his engine, vital to being able to start it.  It had delivered just enough pressure in the morning to get it started the first time, but it was on its last legs.  He had been having trouble starting his SUV in the days leadin ... read more

If you smell gasoline in your vehicle, pay attention to your nose. That's because it has an important message for you. Newer vehicles should never have a gasoline smell inside. One of the most dangerous conditions can come when your fuel line system has a leak or multiple leaks. Vehicles with fuel injectors are under pressure, meaning a crack or small hole in a fuel line can allow vaporized fuel to escape, sometimes around hot engine parts. Gasoline vapor and hot metal? You see the problem. One of the most common causes of a gasoline smell inside a vehicle is a fuel tank leak. The gas tank can rot or be punctured by road debris. A Auto Clinic Care technician can evaluate the condition of your fuel tank and suggest either repair or replacement. Fuel injectors can develop small leaks around their seals or O-rings. Those can deteriorate over time as the material they are made of gets old and less flexible. A technician can replace those parts. Modern vehicles contain something called a ch ... read more
