5 Causes of a Stalled Engine

More often than not, the engine is considered as the most important component of every automobile. The different variations to this principle includes: 1) carbureted engines, 2) engines with distributors, 3) engines equipped with a direct-fire ignition system and 4) fuel-injected engines. Closely associated with automobile engines is the term “stalled engines”, which is in no way a good thing for any driver. With the help of this article, one should be able to identify and avoid the causes of a stalled engine.

Stalled Car EngineFirst things first. The term “stall” is defined as the stopping or slowing down of a process. So when a particular engine is said to be stalled, it simply refers to a situation in which the engine has suddenly ceased operating. For a manual transmission, the sudden take off by the driver from a clutch pedal, whilst in a stationary position, could cause an engine to stall temporarily. Meanwhile, for an automatic transmission, an engine would normally stall when a vehicle travels opposite the direction to which the gear is set. Listed below are the five causes that will cause an engine to stall.

1.     Incorrect Idle Speed

As the most common cause of stalled engine, Incorrect Idle Speed refers to a situation in which the throttle is completely closed while the automobile is idling. This would cause the idle air controller to wear out much faster than it normally should.

2.     Clogged Fuel Filter

Fuel filters should be replaced on a regular interval. For gasoline variants, replacements should occur every six months. On the other hand, diesel variants should have brand new fuel filters every three months or so. However, drivers who overwork their automobiles should perform this requirement more frequently.

3.     Worn Spark Plug

Spark plugs should be checked annually. If any signs of malfunctions should be detected, consider its replacement immediately. We can never accurately predict how a faulty car part could affect the overall performance of a car. In addition, spark plug wires should also be ascertained that wire resistance would not exceed 4,000 ohms per foot of wire.

4.     Vacuum Leak

Vacuum leaks could exist in a fuel-injected system. The process of spotting leaks could be quite tedious and elusive. Some of the tests conducted to discover leaks include smoke tests, drain tests and spray tests. During such tests, carburetor cleaners are sprayed around head-mating surfaces and other locations to determine the source of any possible leaks.

5.     Failure of torque converter

Torque converter is what couples the engine to the drive train. If at any moment it fails to unlock, the vehicle would die down and come to an unwanted halt even before you get the chance to hit the brakes. Extracting fluid out of the radiator would be the appropriate response to this misfortune.

So there you have it – the five causes of a stalled engine. These causes could be quite easy to prevent as long as you maintain your responsibilities as a driver. Have your car checked out at least twice a year. Don’t be a tightwad; replace essential car parts when needed. Never deviate from the instructions indicated in the manual. Happy Driving!
