Ford Ranger Emissions Light is On. Why?

Question

2004 Ford Ranger with 61,000 miles on it. I was filling up today with gas and then added a fuel additive to it. an octane boost i believe that is in an orange contain. five misn later driving away from teh gas station the emissions light came on. Can anyone help me?

Answer 1

I have a Ford Ranger and the check engine light came on after a fill up.Took it to ford and it ended up being the gas.The gas was checked and it had high sulfur content.It is possible that adding the additive and the possible bad gas has made the light come on.It took 2 takes of fresh gas but my light did reset after the problem was corrected.Drive it until the gas is gone.You could check your gas cap it would not hurt but this is what happened to me..Good Luck..

AUTO ZONE do not allow loaner tester any longer.  They claimed Auto Zone was taking business away from "Stealerships" and "rip off auto shops".  They are only selling it but can not return for refund.

Answer 3

Well if the gas cap is on tight.  Just use up the gas you put in and fill it again without the octane boost...  No need for it and the computer is not able to deal with it in my opinion..  

Answer 4

Did you check to make sure the gas cap was tight....???
