Random Check Engine Light?

[zelix]

Hey, i just got my pathfinder out of the shop for spring break... did an oil change and swapped out the spark plugs, put some nice G power platinums in it.

 

Beautiful day today so i decided to explore around the small towns of my province. drove about 250 kilometers today total everything is going fine, also filled the empty tank up with some good shell gas.

 

So as i come back to the city the check engine light comes on. everything is still running fine and the temp looks good (right below half) so i kept driving it home, a block before my house the check engine light then turned off.

 

 

I am confused hehe, is there likely anything wrong? glitch in the computer? or what.

 

Thanks

Check the codes as per the how-to in the garage. Even if the light went off, the code will still be there. Trust me, I've been through this!

I will get on that,

i have noticed however when i fill up with gas and relieve the back pressure in the fuel tank (opening the lid) the light would then go off after a few minutes of driving..
