:mad: I have a 1993 SC with just a K&N filter and a freed up exhaust system and I was wondering why it idles at about 475 RPMs. If u hit the gas, it stops and does not miss. Im thinking that it is a vaccum leak somewhere. Any help would be appreciated. Thanx
 
i would unhook the battery to reset the computer and if its like my 89 check the memory fuse in the fusebox near the battery
