Richard, On my site is a picture of where to set the 02 screw to try to get it back to the original setting. http://www.specialtauto.com/delorean-images/air-flow-adj-2.jpg John Hervey -----Original Message----- From: cruznmd [mailto:racuti1@xxxx] Sent: Saturday, July 26, 2003 1:39 PM To: dmcnews@xxxxxxxxxxxxxxx Subject: [DML] Out. That's right. I'm "out". Out of money, out of ideas and tricks, out of patience. I have replaced the starter, and all of the fuel components. I have spark on all 6 plugs, air and fuel. Too much or too little I don't know because I have no idea where to set the CO screw and it was likely tampered with by the idiot of a mechanic I let work on it in December.
