Troubleshooting Common Chevrolet Cold Air Intake Problems
The air intake system of your Chevrolet is composed of various parts that are prone to having problems. This system is responsible for bringing air into the engine to mix with the fuel. When one part goes wrong, it could have a huge impact to the engine and to the vehicle as a whole. Among these parts is the cold air intake, which helps in getting relatively cold air into the internal-combustion engine. Here are some common issues with the Chevrolet cold air intake and the culprits behind them:
If lately your engine has been acting up and overheats, then there might be something wrong with your cold air intake. Open your hood to check the intake tube located on the left side of the wheel well. Inspect if there are any loose screws or clamps. Tighten them immediately. Check the higher and lower pipes and examine if there are any signs of rust and corrosion.
Engine shuts off
Have you ever experienced your engine shutting off out of nowhere? If yes, then your Chevrolet cold air intake might be clogged. Check the cleanliness of your air flow filter. If it is still white, then it is still clean. If it is already black, then it is excessively dirty. If it is gray, then you're just in time; it needs to be replaced.
A leaking cold air intake can also cause your vehicle to run roughly. Check whether your cold air intake has developed leaks over time by inspecting the parts. Leaks can cause the car to create an unnecessary vacuum. It can also bring water into the engine, which can cause damage and failure. You may also feel the urethane connector with your hand and check for cracks or bubble that can result in leaks.
If you just replaced your stock Chevrolet cold air intake with a new one, then you might experience a couple of issues. It can cause your vehicle to accelerate really slow and even die on you. If you've ever felt like the vehicle is like being held back, then you should try disconnecting the battery for at least 10 minutes so you can reset the fuel trims. Adding a new cold air intake is a major change to the airflow that why the battery needs to be disconnected. Try reinstalling the intake and check if it will work.
A possible culprit of difficulty in driving especially with a cold engine could be a false air entry in the induction system. When the air enters through the connecting pipe between the airflow meter and the throttle body, it will leak into the crankcase. Check if the intake air connector pipe and connections points for the source of the false air. Inspect the vacuum hoses, oil filter cap and dipstick seals for any leaks. See if there are hardened carbon deposits on the rear side of the intake valves that restrict the airflow into the cylinder and absorb fuel vapor.
