I bet you are getting terrible gas mileage, when the front o2 sensors go the ECM defaults to running really rich (hence the lean condition codes).

 

You know what, by that time when i get that code rough terrain, my 3 enemis light was ON, a RH rear sensor was unplug and i was fully lock, t/c was fully lock and all four weeks were locked with ARB! maybe all that made the computer crazy? I don't know is just a taw!!!!

 

Bad mpg!! But also shes been lift, then the roof rack and the 4 hellas 4500 don't hepl at all on higways ijijijjijijiji and plus 33" tires also i'm still running the 3.54 gears , with all that i'm squezing about 310 per tank on higways, I always drive close to truck or sub to get better gas miles, but shes doing about 10 to 12 mpg wich is ok to me
