I was following the steps in Dave S.'s article from an old DeLorean World that said to check it first with the engine off and the RPM relay jumped to engage the lambda system. It's supposed to read 45 like that. That was when it was reading 54 whether I had the WOT switch plugged in or not. The adjustments I made today were with it running hot enough to cycle the fans. I'm just wondering if whatever issue was causing the weird readings when it was cold is something I also have to factor in when it's hot?
