I got a 2004 ranger with the 6 cyl 4L sohc in it. Got my buddy's code reader on it and it's showing codes p0135, p0141, p0155, p0161, p0403, p0446 and p2195, p2197 all at once. Anyone got an idea of what might set all that off at once?

 

Ah that explains it. That's what happens when the spare tire mount and everything attached (evap canister) is going to fall off the truck. Which it did. 3 hours after I posted that question. The wires were chewed up with exposed copper touching. Tire mount all rotted out. I guess that illustrates the importance of washing off the road salt during new england winters.
