Finally, the last area that the Silverado was behind its competitors has finally been upgraded. The interior materials and overall design had been severely lacking in previous model years, and now is one of the most luxurious and ergonomic interiors in the full-size truck class.
One of the factors that have made these trucks so popular is a great assortment of body styles and engines Chevy has been able to offer. With the improvements on the inside, there is nothing that holds this truck out of contention for being possibly the best truck, period.
Consumers who are looking for the ultimate experience from their pickup seriously need to consider one of these trucks. The Chevy Silverado is an impressive workhorse and the comfortable specimen in nearly every category there is.
Diagnosis Chevy Silverado
There are quite a few things that can trigger the Chevy Silverado. Here are the most common problems that will throw the code. They are presented somewhat in order from most to least likely to be causing the code:
- Low Fuel Pressure: If there isn’t enough fuel getting to the engine, this will cause combustion to be less than optimal. Diagnosing low fuel pressure can be tricky. Typically, if you do have low fuel pressure, the vehicle will act fine when it doesn’t need a lot of fuel. But, it’ll sputter and act like it’s going to die at speed or under heavy acceleration. Here’s some information on how to tell if you have a bad fuel filter.
- Vacuum leak: If your Silverado has a vacuum leak, it can be tough for it to get the right air/fuel mixture. This will cause the cylinders to misfire. Also, since a vacuum leak almost always affects each cylinder the same, you’ll typically get P0300 with it and not any cylinder specific misfire codes.
- Ignition Problems: Bad plug wires (if equipped), bad coil packs, and spark plugs can cause misfires to occur. This isn’t higher on the list because typically you’ll get a misfire in one cylinder specifically, and not a P0300 only.
- Cam or Crank Sensors: This one is doubtful, but it does happen. If the ECU is not getting the right signal from these sensors, the vehicle’s timing is not going to sync up, and it’ll misfire.
- Low Compression: If you have a leaking head gasket, bent valve, cracked head, etc.. that would cause compression not to be as high as it should, you’re going to get P0300. You should also feel the vehicle is down on power as well.
- Bad Fuel Injectors: If you have one or more fuel injectors that have gone bad that can certainly cause the air/fuel mixture to go bad.
- Fuel Pump/Fuel Filter: Today’s modern fuel injected motors need a lot of fuel pressure to atomize the gas properly. If the fuel pressure is not as high as it needs to be this atomization doesn’t happen properly, and the optimal air/fuel mixture isn’t achieved.
