Hey Bill, did you store the codes that my car popped up with what you saved? I was just wondering what the exact code was on the EGR one. The O2's I'll replace now that the headers are broken in and I knew about the multiple misfires. But I was thinking if that EGR flow code had been there all along then maybe my EGR is leaking a little or not sealing properly and that led to the multiple misfire situation. But it seems to be running great so who cares about codes!
