Why does my Corvette have a lean misfire?
Why does my Corvette have a lean misfire?
Fuel injectors. If Your Corvette’s battery is faulty or has low voltage, the engine will suffer from a lean misfire. A low voltage battery affects fuel delivery since the fuel pump runs slower than expected. As a result, the fuel pressure is low and a lean fuel condition occurs.
Why are the spark plugs on my Corvette not working?
That happens because the cylinders fail to properly fire, since damaged plugs don’t provide an electric spark that ignites the air/fuel mixture in the engine. The explosion the spark plugs create moves the cylinder down, and the force produced is transferred to your Corvette’s wheels for motion.
What causes damage to the ignition coil in a corvette?
Damaged ignition coils can cause damage to the engine or catalytic converter as well. Ignition coils are prone to damage from voltage overload, caused by faulty spark plugs.
Why does a low voltage battery cause a hard start?
A low voltage battery affects fuel delivery since the fuel pump runs slower than expected. As a result, the fuel pressure is low and a lean fuel condition occurs. In other instances, a low battery hampers the normal opening of fuel injectors, resulting in lean misfire or a hard start.
Why is my Chevy Corvette having battery problems?
My local chevy dealer wanted me to replace the car’s battery, since that was the first code he saw when he scanned the computer. Naturally, the car didn’t need a battery so I drove away from the dealer. The symptom was at any time the car would pop-on the engine trouble light and immediately slow down. The car could only be driven up to 20 mph.

Why does my Corvette not start in cold weather?
Car after sitting in the driveway for more than 7 days will not start in the cold weather (under 45 degree). Bring it to the dealer they charged the battery and cannot reproduce the issue. It happens more than 3 times already. Sometime I have the car towed to the dealership.

Why is my intake camshaft lobe worn on my Corvette?
If an intake camshaft lobe is worn it will not allow fuel and air to be drawn into the cylinder, which will make the engine have a steady miss. From 1972-1981 worn camshaft lobes were a frequent occurrence on small block Chevrolet engines.
Where is the fuel sending unit on a corvette?
The 1975-1981 fuel sending unit is at the top of the fuel tank, which can allow the fuel supply hoses to suck air. This is safer because a deteriorated suction fuel hose will suck air but fuel loss will be minimal.
Why is the Corvette fuel tank higher than the carburetor?
The Corvette fuel tank is slightly higher than the carburetor to allow fuel to be gravity-fed to the carburetor. The fuel tank position will allow idling and low speed performance even with a failed fuel pump.
What causes a fuel pump to leak at the bottom?
Fuel System Leaks Most mechanical fuel pumps have a weep hole on the bottom of the unit. When the internal diaphragm leaks, fuel escapes through the weep hole to notify the vehicle owner of a malfunction. This is one of the more common fuel pump problems found in classic cars that are between 30 and 60 years old.
Where is the weep hole on a fuel pump?
Most mechanical fuel pumps have a weep hole on the bottom of the unit. When the internal diaphragm leaks, fuel escapes through the weep hole to notify the vehicle owner of a malfunction.
How does fuel injection work on a corvette?
The rod length controls when the enrichment lever travels from the economy stop to the power stop. This is similar to setting the timing of the accelerator pump shot on a carburetor. The calibration will affect the settings of the other adjustable features on your fuel injection.
What happens when you blow a spark plug on a corvette?
The explosion the spark plugs create moves the cylinder down, and the force produced is transferred to your Corvette’s wheels for motion. If spark plugs are blown, worn out or loose, your Corvette will misfire.
Damaged ignition coils can cause damage to the engine or catalytic converter as well. Ignition coils are prone to damage from voltage overload, caused by faulty spark plugs.
