The check engine light (service engine soon) comes on and stays on when a problem is detected by the self diagnosis system of your vehicle. Generally, the problem is in the emissions or something that is affecting the effectiveness of the emissions, but other causes can trigger the light to come on, too. To determine the cause, the vehicle will need to be taken to AutoZone or a shop that has an OBD2 scanner, or…
If a Chevrolet Cavalier seems like it is not getting gas when you step on the pedal what could be the problem?
You have a 2004 Cavalier and the check engine light has been on for 8 months now it says emissions large leak when it was checked any ideas?
My car was diagnosed with this problem today also. I was told by my good friend (who is also the mechanic) that the leak could be in many places and the best way to find out where is to complete a test in which 'smoke' is pumped through the system to find the area of the leak. It could be due to a hose disconnected, or, a part in the emissions system could need to…
Global warming is a social problem because of many factors. Factors like emissions for example, emissions tests are only in a few states. With more emissions tests on vehicles, this would lessen the global warming, not by leaps and bounds but it would help. If more people recycled, and cleaned up waters this could help.
If it's weak you might have incomplete combustion or possibly an irratic misfire, but most likely the problem that causes increased emissions is elsewhere. An increase in hydrocarbons is often caused by the O2 sensor or possibly the EGR valve. You could also have a problem with plugs, distributor, rotor or plug wires.

SOMETIMES a Lazy O2 sensor(oxygen sensor) will turn on a check engine & then go OFF - but SOMETIMES it will SET a Hard Code.U need 2 check the History of codes in the Computer It could be the Thermostat. I had a firebird that had the same problem. Turns out the thermostat was too cold. There is a problem that is affecting the emissions system. There are a multitude of possiblities as to why…
Emissions problem. Have the computer scanned for trouble codes. Under the dash on the drivers side there is a fuse block and there is a empty spot in the block that has ridges around it. put a spare fuse in it and turn the key but dont start the car and watch the check engine light it will flash the codes. Like Blink----BlinkBlink, which is a code 12 which is a no trouble code.
