An engine that struggles to start, runs roughly, or suddenly loses power can have several possible problems. Sometimes the issue comes from the fuel system or ignition components. Other times, a weak cylinder may be the reason the engine is not running properly. This is where Relative Compression Testing vs

A truck can pull well all morning, then struggle on one hill. Minutes later, it feels fine again. That is what makes intermittent diesel power loss so frustrating. The problem may disappear before anyone opens the hood. Finding the cause takes more than reading a fault code. Technicians study when

A truck feels weak pulling away, but the scan tool shows dozens of changing numbers. Which ones matter? Understanding diesel engine live data starts with a simple question: what is the computer asking for, and what does it report happening? At Kepkee’s Diesel & Performance, our message is simple. A

A warning light comes on, and your scanner names a sensor. Replacing that sensor might seem like the next step. But diesel trouble codes describe what the computer detected. They do not always identify the part that caused it. At Kepkee’s Diesel & Performance, our approach starts with a simple

A diesel engine needs a steady supply of clean fuel to run correctly. The fuel must first travel from the tank to the engine. It then has to be raised to very high pressure before the injectors can spray it into the cylinders. If something goes wrong during either step,

A diesel particulate filter, usually called a DPF, captures soot from the exhaust before it can leave the tailpipe. Once enough soot collects, the truck raises the exhaust temperature and burns much of it away. That cleaning process is called regeneration. It is normal, but frequent DPF regeneration can be

If you own a diesel truck, you have probably heard about DPF regeneration. Maybe your truck has gone through a regen while you were driving. Maybe you have even dealt with a warning light telling you the diesel particulate filter is getting full. But there is one part that causes

Your diesel truck feels slower than usual. You press the pedal, but the power does not arrive the way it used to. Then a warning light appears. Perhaps the truck has stored a P0299 code too. The first thought is often, “The turbo is bad.” That is possible. Still, a

A diesel engine that takes too long to start is trying to tell you something. Sometimes the problem only happens first thing in the morning. Other times, the truck starts fine cold, then struggles after you drive it and shut it off for a few minutes. Those two situations often
