Question about 1995 Pontiac Sunfire

Check engine light

Ok i know it would probably be the easiest to just get a code computer to read the code but the light only comes on when the car is on the highway or at speeds of 50+ mph when the light comes on the lights on the car dim really quick. and i noticed the car isnt getting as good as gas miliage know eather only 20mpg on highway. i replaced the plugs and wires i put a new map sensor in the car. anyonther ideas? i do think it might be the computer it self. so any answers might help thanks

Without the actual code I'd be guessing. Very unprofessional to me and certainly not fair to you. I can tell you how to fix what's wrong with your car, but I need the actual code or codes.

    You don't need a scanner. Even though you're cheap (like most people) all you need is a jumper lead. It's an OBD I system, not an OBD II system. If it was OBD II then you would need a scan tool. In that case most of the chain type auto repair stores would do a scan for free.

Service engine soon light was on and now went off? what is the problem?


Often times it is a loose gas cap. Have you refueled between the light going on and going off? You probably fixed your problem.

How reset check engine light


The easiest way to reset a check engine light on almost any modern car is to disconnect the battery wait five minutes and connect it back up. This will not tell you why the check engine light came on. For that you need a ODBII scanner, but if the issue was a gas cap left off and you have fixed that, then check engine the light should go off. I have found that many auto parts stores will read your car's ODBII codes for free.

2000 Chrysler Concorde, The battery caused a fire, fixed that problem, but now check engine light comes on, and sputters a bit. Any suggestions?


The easiest way to figure this out is to read the touble code that triggered the check engine light.You will probably want to clear the code after making the correction,otherwise,it colud take a lot of ignition cycles to go out on its own.A basic code scanner is about 50 bucks,which will pay for itself in one use! The battery fire probably melted a nearby wire,connector,or sensor.

The warning light that looks like an engine is lit up


That is your "Check Engine Light" / "Service Engine Light". It means the Computer (ECM / PCM / ECU, it goes by many names) has detected a problem with one or more parts on the engine or transmission.
The easiest way to find out, is to stop by an auto parts store (like Advance Auto, Auto Zone, etc) and have them hook up a Scan Tool to read the Trouble Codes from the ECM. They do that for free. Most if not all garages/mechanics also have the necessary Scan Tool as well, but most of those will charge you just to read the codes.

What are the possible causes for the check engine light coming on? 1998 Ford Explorer Sport 4wd


Hi there,

The Engine Check Light (or MIL) triggers when your on-board vehicle computer has determined either a malfunction (or out of spec condition) of one of your engine and/or emission circuits. This can range from minor, to more serious.

Due to the number of circuits monitored by your computer, the possible causes are many and answering your question would be difficult without first connecting a scan tool (or similar) to 'read' the stored codes.

These codes will immediately identify which circuit (or circuits) are causing this condition.

I recommend you have an authorised Ford agent (with the appropriate scan tool) to read your codes - this will only take around 15-30mins (depending on the experience of the technician).


Good luck,

Ran out of gas recently. when refueled and started again,check engine symbol stayed on? well mainted and has always ran great since new.


Sometimes the check engine light will come on if the fuel cap is not on tight enough. Check the fuel cap for an intact seal and install at correct tightness.

A major auto parts store will read out the stored trouble code in the car's computer for free. If the code pertains to the fuel EVAP system, the code probably set because you ran out of gas. Copy down the code and then have it erased. The check engine light should go out. If it comes on again, have the code read and the problem checked out.

Engine check light comes on when starting and remains on until engine gets warm or about 5 minutes engine running and then warning light is off.


what year is the vehicle and the engine size? It may be the o2 sensor, these are usually heated so they read correctly under cold startup conditions. The heater in the unit probably failed however this usually trips a hard code and stays in the computer until it is deleted with a computer.

Goto a local auto parts store and have them scan your cars computer and see if there are any codes. This is usually the easiest way to find out what is wrong.

Good luck!

Check engine light is and my s1 light is on in the drive


If your check engine light is on then it means that there are codes stored in the computer. The easiest way to find out what they are is to go to an Advance Auto Parts Store or Autozone as I know they will read the codes and tell you what they are for free. If you do not have one of those stores around you I would suggest finding any auto parts store that offers a free diagnostic check. Once you know the code then you will be able to fix the problem. I am not sure why the S1 light is coming on but I do know that the first step to fixing your problem will be to get the codes read. otherwise you will just keep guessing. Hope this helps.
