KIA Check Engine Light On Again

My question is my Kia has 108,000 miles on it and I bought a few months ago and I have had a gas smell coming through the vents we have checked everything all tight and no leaks..my dad thinks it might be a pcv valve what do you think?

My engine light stays on, I have gotten gas and left the gas cap off for a few miles home and it seems to go away for awhile it does it more when its cold or gets down low on gas. My gas mileage sucks right now and at $4 a gallon I need to fix this, I cant afford a mechanic so my great dad is trying to help me but its hard on the newer cars so any help you can give me would so be appreciated.

Thanks Teresa

 

Hey there Teresa,

I don’t think you have a problem with the PCV valve, that helps ventilate the exhaust gases inside the engine, but I don’t think it is the culprit here. First things first…you are going to have to get the on board computer codes read and see what the computer sees as the problem. Yes, leaving the gas cap loose can cause the check engine light to come on, but it will not affect fuel mileage, so you probably have something else going on here.

Unfortunately the only thing I can suggest is to see a mechanic, have them read the computer codes and diagnose the problem for you. I would NOT go to a fast lube place or a franchise auto parts place claiming they can do computer diagnosis….most of those places can not! You will just spend your time and money guessing at parts. I would go to the dealership OR a qualified KIA mechanic, trust me you will save money in the long run.

Blessings,
