This is true. I would not trust a used cat.
Another thing I didn't think of that could be causing the bad fuel economy is a failing or clogged MAF. If your MAF isn't working properly, your ECU might be running the car extra rich to prevent detonation. Just another idea. But definitely take it to a (professional) mechanic and have him/her check it out. |
