2004 chev optra vacuum lines...
I have a 2004 chevrolet Optra OPL and have an intermittant check engine light.
I found a vacuum line wrapped around the battery, its a small line coming out of the top
of the vacuum compressor. where does it go? sometimes if i put a screw in it the
check engine light will go off, until it comes on again.
there has to be only one place where it needs to go.... arg...
