1995 Chevy Corsica 6 cyl Four Wheel Drive Automatic? Miles

The reason I'm emailing you is I've never had any problems with my car up until I got ethanol in my gas tank. I was told once I would either burn the fuel out of my car or drain it out that everything would be fine. I've had to go to the extent of replacing the fuel filter which was never the problem to begin with. The fuel filter or the even the air filter was never dirty. But I was told that it took a toll on the fuel pump. This has been replaced but never helped. I've replaced the spark plugs. This didn't help either. Now I'm told it could be a sensor. The question is which one? All the diagnostic testing are showing no trouble code found. Can a sensor be weak or something? What the car does when I go to start it up it dies on me. It's a battle of keeping it started. It behaves like a car in the winter. & This all began when it was around a 100 degrees outside. & It's still giving me trouble. I feel it's gonna get worse once winter hits. If I can keep my car started once I get it warmed up I'm ok. Until it cools off. It's worse after setting over night. I was told my motor was sticking. & At the shop the motor was cleaned. But I found out this wasn't the problem at all. I was told it's hard to detect if it's a sensor while my car is running. I was told the ethanol had throwed all the trash that it's collected through out the years on my engine. I'm at a dead end. Because my car is stll running the sameway it has ever since I put the ethanol in my tank. I was told my car isn't old enough for this to take a toll on it. & Stores are only selling 10 percent. But I was told they can't sell more then that anyway. All I know is something isn't right. This car has left me stranded. So I know there is something wrong. Trying to get my car started I know has to be taking a toll on it also like the starter. If you can give me some idea over what it could be. OR what I can have checked out I'd appreciate this so so much.

Thank you,

Karen Johnson

Could be the oxygen sensor is working, but is out of range, so it wont set a code. Unfortunatly without any codes it will be hard to diagnose. Find a shop that has a scanner that can watch the sensors to try to see which one isnt working properly

That does make alot of sense if my sensor isn't showing up on the diagnostic testing. I was told at this shop that if my car is still giving me any trouble to bring it back for them to keep it over night. & Their hoping they would be able to find the exact problem then. What u described sounds like it could be the problem. Because everyone has checked my car over & said they couldn't find anything wrong. But the way it runs I defintely know there isn't something right. I appreciate your help.

Thank you so much,

Karen
