Hello everyone. First time poster here. Decided to come here because getting alot of mixed info otherwise and figured I might get something more specific and helpful info here. We have an 02' Mountaineer with 4.6 and just started running rough last night upon startup. Just replaced intake manifold not too long ago with all new boots an plugs. Drove it today to get it scanned and run pretty much completely fine. Scanned codes and threw a P0172 "system too rich bank 1". Saw posts on here for 4.0s and so but thought I'd make my own to get more direct help hopefully. Thanks in advance
