I want some opinions on what my check engine could be about.
I got my.truck a few days ago and some
friends were revving it quite a bit after a
little bit the check engine light came on I
unplugged the battery for about 5 minutes
and it went away but came.back on then I
went to my mechanic and he plugged it in
and said something about vapor he cleared
it and it shut off for a couple hours but
came back on
He is most likely referring to the vapor system from the fuel tank, the most common is the solenoid valve in the vapor line that goes to the intake manifold, sometimes you can clean it and it will work but usually it has to be replaced.
