Check engine light problem
2003 cavalier.
The check engine light won't turn off, took it to auto zone and the meter thing said it was a faulty gas cap. I replaced it and it still won't turn off after several weeks.
I hear a hissing sound coming from underneath the dash. The battery isn't good also if that could cause a problem with the check engine light.
Edit
the hissing noise starts when I turn on the ac. Which the air conditioning does not work. Vacuum leak maybe?
Any help is very much appreciated
