Engine has low output (power)

Today's engines have been designed to have more output power and lower emissions then ever before. So when the output of your vehicles engine is compromised it is easily detected. When your vehicle has low power output it can mean several different things are occurring. What you should know is while your car has low performance it could be damaging your vehicle the longer you operate it. Example: The emergency brake is on and you did not notice, this condition will burn up the rear brake pads or shoes and cause premature brake failure. Or, the fuel filter is clogged and the fuel pump is laboring and causes premature pump failure.

Several conditions can cause low power, one of the most popular is the fuel filter is clogged not allowing the proper amount of fuel pressure and volume into the fuel injection system. Next, the exhaust system is clogged not allowing exhaust gasses to exit the system properly. Most exhaust clogging problems are caused by the catalectic converter, but we have seen a muffler or two cause problems. The fuel system could be lean or severely rich causing improper fuel combustion. Next, the spark timing could be maladjusted, but most vehicles today have crank trigger systems, (no adjustment required). And the air filter could be plugged causing low air intake not letting the engine breath properly. Plus the fuel pump could be faltering providing low system fuel pressure, low fuel, low power. If the engine is worn out, when engines exceed there life expectancy the compression is compromised (low compression) causing low power output.

Common problems

1. plugged fuel filter causing low fuel pressure in the fuel injection system.

2. plugged air filter not allowing the proper amount of air into the engine.

3. fuel pump is worn providing low fuel pressure to the fuel injectors.
