Service engine light :(
Today my service engine light just come on.
It happened right after i filled up with gas...
I went to advance and had them to run the test and they said trouble code P1285
I really dont have any mods other than a cold air intake.
but i put it on a month ago and it just come on today...
well the guy at advance took the light off. I put a little more gas in my car and it came back on.
What can be the problem?
Is it bad?
