Question about 2002 Kia Rio
So, I replaced the air filter in the car, and had an oil change done. 3 days later the CHECK ENGINE light came on. It stayed on for 1.5 days. I checked (and topped up) all fluid levels (which were all normal anyways). The next day, the check engine light was still on when I went to work, but when I drove to a friends for lunch, it wasn't on (and hasn't been on since)...a friend of mine said it was possibly a faulty censor..what do you think?
ps...the car is running as normal..no stalls,no leaks and no weird smells...
This could be an O2 sensor or sometimes with lower grade gasoline I have seen different cars act this way. If the O2 is not bad try mid to super gas or fuel system treatment/cleaner to see if there is a change. I know in my area there is mostly 10% ethanol which will lower octane. I hope this helps!
