>> 1500 ish is typical for passenger car idle. > >Not on any car I've ever driven, it isn't! :-) Me too - any car I have owned has always had an idle under 1000 rpm, unless the choke was pulled out on ones that had manual choke. I've always regarded around 750 rpm to be normal idle, sometimes it can be slower on a well tuned engine. -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
