I have a 94 Mark and i am getting 8.5 mpg. I pulled the codes and they are 172, #1 cat bank lean, 176 #2 cat bank lean, and 524 and 543 which I have read up on in other post. they say the o2's can cause these codes. can bad o2's cause my fuel economy to be this low? new to lincolns i have always been a chevy guy. but after years of helping Jeff (sierra3) i broke down and had to get one. thanks in advance.
