Check engine light on after adding #91 gas to a 05 honda accord?
I normally just use #87, under which my car runs pretty good. However to see the difference of premium gas i added about 10 gallons #91 mixing with 5 gallons of #87 which was originally in the tank to my car. After few minutes of driving check engine light was on. Could #91 gas caused it? What should I do?
I think you probably left the gas cap loose but get the codes read, won't be the gas either way.
Check you fuel cap othewise it is coincident.
The higher octane gas is NOT a problem in that vehicle. It won't go any better with it, but it won't be causing a problem either.
A loose gas cap is possible, and easy to check. Otherwise you need to get the computer's error codes read, and work from there.
That will not cause a check engine light to go on. Maybe if there was already some problem like with a MAF sensor, and the change in gas just caused it to happen sooner?
Get the code read at an auto parts store, they usually do them for free, or you local garage.
Get your codes read. Probably just a conincidence. Accords will take any fuel.
The gas didn't cause it.Don't blame the gas.blame the light.Put an OBD scanner on it to ask the car why the light is activated.
- Check engine light, open door light, and batterie light all came on and won't go off? 2000 Honda Odyssey I already had the altinator replaced it a month old. The batterie almost a year old. Would the belt need be changed or something else?
- Flashing check engine light on 02 Honda Oddyssey after Valvoline oil change? Got an oil change at Valvoline, and next day check engine light began flashing. Car was running flawlessly before oil change. They suggested a new fuel filter, as mine was pretty rough. I declined. Got error codes of random misfire, as well as cylinder 1,2,4,6 misfire. Scanner at auto zone listed EGR valve as suggested part. Could this possibly be that the fuel filter is bad or was put back on incorrectly?
- Check engine light not going off on my 97 Honda Civic even after fixing problem? Cranking and starting my Civic made the check engine light come on and sputter and idle real bad. Figured it might be a bad fuel filter so I changed the thing and now it runs smoothly again but that check engine light is still on. Can there still a problem? Do i need to reset something to make the light go off?
- My check engine light was flashing yesterday and now it's off, and today my red oil change light was flashing earlier and then stopped? What does that mean? I drive a Honda Accord, if that helps. My car is driving fine (just a slight jerking every now and then, but that's another issue i'll get fixed). The fact that it did that then stopped worries me… Help?!
