Welcome,
Please go to your control panel and enter some info about your car.. make model engine number of miles. This way when you ask a question we'll have a little something to go by and we can be more specific in our responses.
Please bookmark this site in your favorites. Often people join, ask a question and forget where they were and never come back for their solution.
Great to have you here!
Pull Diagnostic Trouble Codes (DTCs) From your onboard computer.
Your engine and transmission are computer controlled.
The computer uses sensors to tell it a number of different things and it controls actuators that push or pull mechanical levers (kinda). If one or more sensors aren't working properly, the computer goes "blind" and doesn't know what to do. If the computer can "see" but one of the actuators is broken and therefore can't follow the commands of the computer; the engine won't run correctly. The computer is preprogrammed with set values for each of its sensors, and each of its actuators. It will run a self check of all systems, like the space shuttle; it will compare its set value(s) to the value(s) it recieves from its sensors, and actuators. If any sensor or acutator is out of the "normal" range the computer will generate a "code." It will generate some codes on the fly, and others will be stored while you are driving.
Some auto parts stores will scan your engine codes for FREE, you may want to call around.
