My check engine light in my 2001 vert has been coming on. I erased it but keeps coming back. I guess its not going to fix itself. I know it has something to do with the AIR pump or relay circuit. I'm just wondering if there is a common problem here that could easily be fixed. I wont try anything untill I get my advice from the forum! I've learned my lessons on that... Thanks in advance.
Im having the same problem... Check for corroded lines under your battery. Also could be a check valve that needs lubed... There are a few fixes in the search section.
