GDI Carbon Buildup: Why Direct Injection Engines Gradually Lose Power, Efficiency, and Reliability Gasoline Direct Injection (GDI) engines have become the standard across most modern vehicle platforms. Automakers adopted this technology to improve fuel efficiency, increase power output, and meet increasingly strict emissions regulations. While GDI engines deliver impressive performance when new, they carry an inherent downside that many drivers do not discover until drivability issues begin to surface: carbon buildup. Most drivers notice the problem slowly. Idle becomes rough. Acceleration feels delayed. Power fades under load. The check engine light may appear and disappear without a clear explanation. These symptoms are often blamed on spark plugs, coils, sensors, or fuel quality. In reality, the root cause is frequently hidden inside the intake system. In areas like Clackamas and the surrounding Portland metro region—where short trips, heavy traffic, cooler weather, and sto ... read more

Engine Diagnostics: A Complete Guide for Clackamas, Happy Valley, and the Greater Portland Metro Modern engines are more advanced than at any point in automotive history. What once relied on mechanical linkages, simple carburetors, and basic ignition systems is now controlled by a complex, computer-managed network of sensors, actuators, modules, and real-time data. Every second your engine runs, hundreds of processes must operate in harmony—fuel delivery, timing, airflow, combustion, temperature regulation, emissions, electrical communication, and more. Because of this complexity, engine diagnostics have become essential. When something goes wrong, the vehicle communicates through symptoms, warning lights, and behavior changes. But those symptoms must be interpreted correctly. That is the job of a complete diagnostic evaluation. Most drivers misunderstand what diagnostics actually mean. They associate diagnostics with a quick code scan. But a code is not a diagnosis. A code do ... read more

Can I Drive With a Check Engine Light On?

Is It Safe to Drive With a Steering Wheel Shake? A steering wheel that shakes while driving is one of those symptoms drivers notice immediately—and often try to tolerate longer than they should. Sometimes it’s mild and easy to dismiss. Other times, it’s the first sign that steering or braking control isn’t as stable as it needs to be. The difficulty is that not all steering wheel shakes mean the same thing. Some are relatively low risk and stable. Others are early warnings of issues that can affect safety, reliability, and long-term repair outcomes. This guide explains how to tell the difference, what’s usually happening mechanically, and how to decide what to do next without guessing or rushing into unnecessary repairs.     The clear, honest answer Driving with a steering wheel shake is sometimes acceptable short-term and sometimes not safe at all. The difference depends on when the vibration happens, how it feels, and whether it’s c ... read more
