DOES A PROBLEM WITH CAT. CONVERT. AFFECT GAS MILEAGE?

Question

i have a 2000 maxima, and i have this engine light on. i went and had it check and it was my calatytic converter bank 2 that needed to be changed. the average price is about $800-$900 to have that part replaced. who has that kind of money nowadays??? lol

but i need to know if it's going to have a bad effect on my gas mileage.

what are my options here, if i don't have that part fixed right away? and will my MPG go down because of that problem?

please help!

Answer 1

Having a bad converter can effect you're mpg, will mostly effect the emissions, but if you're state has emission laws you would need to get it fixed. just how much it would effect you're mpg would depend on you're driving habits. Did you notice any difference in the gas mileage since you're check engine light came on? Is what I always do,is first take it to my locale O'Reillys and barrow there code reader(it's a smaller computer so it just gives basic idea), and  that will give a general idea of what is wrong and take that to the shop or dealer.  

Answer 2

A stopped up Cat Conv can hurt mileage and can ultimately cause your car to strand you.
