My wideband goes off the chart on the rich side for the first 15 miles or so every time i get a full tank of gas, and come down to idle. Any ideas on what this is caused by, after a few miles problem goes away, and i sit right around 14.7 at idle? Stock fuel pump, and no AFPR, I do have 550s and lexus, but they seem to be running as expected without a piggy back. ONce i get the tool ill post my base fuel pressure. :wtf:
