I've used this site numerous times to help with issues, so I thought I might as well join. I just picked up my second volvo today, a 1990 740 turbo which is replacing my 1990 240 dl wagon. I've got some issues with the 740 so if anyone can offer suggestions on low idle (~700-800rpm) and tell me some common issues to look for it would be greatly appreciated.
