2001 Pontiac Sunfire. Engine Warning light comes ...

2001 Pontiac Sunfire. Engine Warning light comes on when I use gasoline with ethanol. Does not come on when I use gasoline without ethanol. Since more and more companies are now using ethanol I will soon have the light on all the time. Is there another way to prevent the light from coming on with ethanol laced gas.

When the light is on you need to pull the OBD codes with a code reader or go to an autopart store and have them do it. With that in mind ethanol changes the exhaust coming out of the engine, the ethanol causes the oxygen to be higher in the exhaust than is expected and the light comes on. You should have the codes checked to be sure. However there is no damage coming from this light, if that is the cause.

SOURCE: Put in new stereo in 2001 Pontiac Sunfire now have no panel

Did you use a special wire harness? GM connected some computer system wiring with the stereo system, so if you replace this, there will be no chime when you open your door with the headlights on or keys in the ignition...and some other warning stuff. This special harness can be bought, but it is expensive (around 80-150$). Go to electronics store and ask for one. Anyways, hope this helps.

SOURCE: A/C Orifice Tube on Sunfire

Pontiac has bad habit of moving them around on us. 
Example: on the 2000 Sunfire it is at the outlet of the condenser up near the front of the car. On the 1998 it is on the high pressure line right as it enters the firewall.
Therefore I am comfortable in saying that you will find it in the outlet of the condenser up near the front of the car.I recommend that if you are doing this repair yourself, ensure you replace the o-ring on the line itself with a new one. 
 Thank you for your question and good luck.

SOURCE: check automatic transmission fluid 2001 pontiac sunfire

You need to raise the vehicle and start it. Remove the plug near where the passenger side driveshaft comes out. The head of the plug is 7/16. Trans fluid will stream out of the hole when the engine is running when the transmission is full, If fluid doesn't run out, fill the trans until fluid runs out. The fill cap is red and it is on top under and around the air cleaner box. If you need more help let me know.

Check engine light has gone on, what could be wrong

A check engine light could be illuminated for 100+ different reasons probably, can you describe more about any problems you might be experiencing along with that warning light? Knocking sounds, engine running rough, poor acceleration ect. Also, does the check engine light blink at any point in time? If your vehicle is in operable condition you can take your vehicle to certain part stores such as Autozone that offers free code scans to better diagnose warning codes.

How do you reset the check engine light on a 2001 Pontiac sunfire after oil change

Well the check engine light is not on because the engine oil needs to be changed. The light is warning the driver the computer has found a problem that can affect performance and emissions.
The computer has to be scanned for trouble codes then the problem has to be fixed before the light can be turned off.

2003 Sunfire automatic 245000km runs well, engine stops while driving, clicking under the dash, then restarts , runs fine until next time

with the details that you have provided, it sounds like it may be either a ground, or ignition relay, but I've also encountered the same problem being the starter wire to the starter. The reason I think that is because of your dash lights coming back on .If you have use of a voltmeter you can test and see how much power is actually going to the starter An ignition relay could do the same, but usually won't interrupt the engine after it's running.

2001 pontiac sunfire abs and check engine light is on. brake fluid is full and the front brakes were just changed about a month ago.

I think these lights are not related. The ABS light means the ABS is not working, and has nothing to do with the brakes working. You can have brakes and not have the ABS part working. I don't think a bad ABS would turn on the check engine light, but it may.
