The purpose of the intake manifold, or inlet manifold, is to evenly distribute the air-fuel mixture to the cylinders as well as to the carburetor on a non-fuel-injected engine. An intake manifold is the opposite of an exhaust manifold, which collects gases from the cylinders.


Symptoms of an intake manifold gasket leak include poor engine performance, engine overheating and coolant leaks. The leak allows additional air to mix with the fuel-air mix, causing the engine to run lean. On vehicles with onboard diagnostics, the leak often causes the check engine light to illumin


A tri-power intake manifold refers to an intake manifold with three carburetors. The design was first used by Pontiac and is most often found in specialty models of American cars from the 1950s and 1960s. Some auto companies sold tri-power systems with three two-barrel carburetors.


Engine backfire is caused by an imbalance in the air-to-fuel ratio of the vehicle. Backfires occur in one of two places. A backfire in the intake manifold is caused by a ratio that is too lean (not enough fuel). A backfire out of the exhaust system is caused by a ratio that is too rich (too much fue


No part or type of manifold in a car engine is typically referred to as a torque intake manifold. An intake manifold or inlet manifold is a series of tubes in an automobile responsible for supplying and in some cases evenly distributing the fuel and air mixture into an engine's cylinders.


Cars backfire for several reasons, including air and fuel mixing due to leaking hoses or other mechanical problems. Faulty spark plugs or wires can cause a car to backfire. It can also occur when shifting to a lower gear in a car with high horsepower.


An intake manifold runner control is an electronic system that gives data regarding linkage and plate position to the powertrain control module. The IMRC is housed inside an aluminium casting that stores a motorized actuator with air passages for each cylinder. The IMRC does not become active at eng


When the explosive noise of a car backfire occurs, it usually indicates that the air-to-fuel mixture is unbalanced or that a problem exists with the vehicle's timing. A backfire is the result of fuel burning outside to the engine's combustion chamber. Backfires can occur in either the intake system


The two most common symptoms of intake manifold gaskets failing are sluggish acceleration and coolant loss. When an intake manifold gasket fails, the leak causes extra air to be sucked into the engine. This causes a decrease in gas going into the cylinders and makes the acceleration respond slowly.


Backfiring during acceleration occurs when ignition takes place in the intake or exhaust instead of the combustion chamber. The most common causes for backfiring during acceleration include an incorrect fuel-to-air ratio, a faulty ignition and bad wiring.
