Can you reset the Service Engine Soon light on a 2003 Mitsubishi Galant GTZ without taking it to a dealership?

I have a 2002 Galant GTZ - basically the same car. Disconnect the battery cable for a period of time. This will clear out the computer's memory and reset the light. If the light continues to come back on afterwards, then you might want to get it checked. I've done this on my Galant as well as a 1999 Jeep Cherokee and 1999 Dodge Avenger. I think it will work on any car where the engine light doesn't turn off unless externally reset. When I've done it, I've had the battery cable off for as long as overnight and short as 4 or 5 hours. Just depended on when I disconnected it and when I needed to drive it again. May be able to do it for less time. Just need it to be long enough for the computer to lose it's memory. Of course, you'll lose your radio presets as well.

Your Check engine light came on then went off several miles later what does this mean?

Open and read your owner's manual and you will find the answer The check engine light comes on when the computer diagnostic has stored an error code. It can be something as simple as the battery has been disconnected recently or something to do with the emissions controls. One way for you to find out is by checking the codes yourself. IT may help to point you in the right direction. This page gives the procedure and some of the codes. Of course, if none of this means anything to you, you can always have to dealer hook it up to their diagnostics. http://www.allpar.com/fix/80s-codes.html Take it to auto parts store they have the same diagnostic code reader and its a free check..

Why is the Check engine light blinking on 2001 blazer?

When the check engine light or MIL (Malfunction Indicator Lamp) is blinking approximately once every second it is indicating what is called a Type A Misfire. A misfire occurs when one or more cylinders is not contributing to the power output of the engine. Type A misfires are damaging to the catalytic converter on the vehicle and are therefore deemed very harmful. Misfires can be caused by a variety of things but can generally be classified into one of three categories: Fuel, Ignition, Base Engine. Fuel could be a malfunctioning injector for example. An ignition example could be a spark plug that is not firing due to a bad ignition coil. A base engine example could be a bent connecting rod or a hole in a piston. Catalytic converters can be quite expensive to replace so might want to get it repaired sooner rather than later.
