New aftermarket exhaust installed and pulling lean codes on 2004 ram 1500
I just installed pacesetter headers with 3" pipe all the back. I'm pulling lean codes P1074 I believe it was. I had bungs welded in behind the cat to accommodate the downstream o2 sensors, but I cannot figure out why I'm running lean. Mpg dropped to average 6 mpg idles around 600rpm (rough) and lags a bit when I get on the gas. Please help with this issue...
