Common Reasons for Check Engine Lights

Friday, February 26th, 2016

“Check engine” light on? If so, you’re probably scratching your head wondering what could possibly be the problem. The fact of the matter is there are numerous reasons why your vehicle’s engine warning light might be on. The best way to know for sure what’s caused the check engine light is to visit your local automotive repair shop in Tucson and have a professional technician perform an advanced computer diagnostic scan. There are literally hundreds of different reasons why the check engine light may come on, but here are four of the most common:

Gas Cap is Loose or Damaged

Believe it or not, one of the most common reasons for a check engine light is a loose, damaged, or missing gas cap. If your gas cap is damaged or missing, replace it and see if that solves the check engine warning. It’s also a good idea to replace damaged or missing gas caps since you can lose fuel through evaporation without a tight seal.

used spark plugs

Dirty Spark Plugs or Plug Wires

If you are experiencing reduced power, lower fuel economy, and other noticeable performance issues while your check engine light is on, the problem might be dirty or worn out spark plugs and/or plug wires. If you don’t know how to check or replace spark plugs and plug wires, bring your vehicle to an automotive repair shop for this service.

Bad Sensors

There are two primary sensors that can cause the check engine light to come on when they fail. The mass airflow sensor measures the amount of air entering the engine, and the oxygen sensor measures the amount of unburned oxygen in the car’s exhaust system. A computer diagnostic scan is needed to determine whether a faulty sensor is the cause of the problem.

Spotting the Signs of a Carburetor Problem

Friday, February 12th, 2016

If you drive an older vehicle, you have to worry about car troubles that most owners of modern vehicles have probably never heard of. For example, vehicles built prior to the mid-1980s utilize an engine component that hasn’t been in new production vehicles for close to 30 years. A carburetor pulls air into the engine where it is mixed with fuel before flowing into the cylinders where it is burned to produce power. Carburetors were replaced by throttle body and multiport electronic fuel injections systems by the mid-80s, but owners of older vehicles will need to be on the lookout for signs of carburetor problems. Visit an automotive repair shop in Tucson if you notice any of the following signs:

Cold Starting Problems

Trouble starting your vehicle on cold mornings can be caused by a choke mechanism within the carburetor that fails to close and causes a rich fuel mixture when the engine is cold. The good news is that carburetor problem is fast and inexpensive to repair.

Hesitation When Accelerating

One of the most telling symptoms of a bad carburetor is hesitation when accelerating. This is typically the result of a lean fuel mixture, which means too much air and not enough fuel. A weak accelerator pump, worn throttle shafts, or dirt inside the carburetor are a few of the problems that might be causing the poor air/fuel mixture.

Rough Idle

Another recognizable sign of carburetor trouble is rough idling. In other words, if your engine is shaking, sputtering, or otherwise acting up when your vehicle is at a stop, you’ll need to bring your vehicle to a repair shop to have the carburetor looked at. This problem can also be caused an overly lean fuel mixture.
