Replacing your catalytic converter will not resolve your excess fuel consumption problem. Cats only assist in emissions, and excess fuel that gets to them, breaks them down. Therefore, you need to find out your fuel problem to no longer replace the cat.
Could have leaking fuel injectors, or bad valves which do not allow for a better and complete combustion. Bad sensors could also cause problems.
Start out by performing a complete and proper tune up. Then check to see if you have any codes in your ECM.
Ok thank you, I appreciate your help

SOURCE: catalytic converter replacement
Good day
please disregard my last post. The only thing that came up was " the driver side catalytic converter on my 2003 ford expedition" so I was trying to fine out what you were asking, then I came across this full one.
Cheers

SOURCE: is it true that ford escape's catalytic converter
no a dealer is not the only place that replaces these; you can do it yourself and there should be 2 of them. most of them are replaced with aftermarket ones. go to a muffler shop and they will replace them for you and you can check at an Autozone or Napa for the catalytic converters

3 front coils? Ignition coils? If the engine had a miss for a long time the excess fuel can ruin a catalytic converter.
SOURCE: 2007 kia rondo seems to use alot of gas
I have the same issue of low gas mileage. My 2008 Kia Rondo with V6 (2.7Lt) gets 20-21 mpg in average. Even for highway mileage, it is around 21-22mpg. Very poor gas mileage. Disappointed. I hope it would improve in the future.
