You are going to have to find out what the DTC (Diagnostic Trouble Code) is that is causing the CEL to turn on. If you do not have a code reader, or know someone who does, you might want to consider getting one if you are going to be keeping your Civic for any length of time. There are some places that will read the code for free (I think AAMCO will do it for free).

Once you get the code, you will know exactly what the malfunction is and you'll be able to address it directly.

best answer here is that the sensors are not set for the poor quality fuel ( the octane ratine is probably to low for the ECM to properly maintain the air /fuel mixture ) you have the answer to your problem when you change back to quality fuel and it runs right. As a point of interest most small engines will not run right on e fuel mixes.

Needs to know the best recommended fuel type for my toyota corolla 1993 model


Hi!!

You should be using regular unleaded. This is "regular" 87-octane gasoline. You have no reason to need gas with a higher octane, it would be a waste, stick to 87.

Good luck!!

Sounds like it could be vapor locking. Especially if it starts after it gets cool. Try adding a can of octane booster to the fuel next time you fill up and see if that helps.

Moisture can cause a lot of problems.... try drying out all the ignition parts you can. then re start and see if problem goes away. Hood up on a hot sunny day can do wonders!
