98 F150 4x4 LariatThe cat converter on my 98 makes a loud like pinging noise when im in idle. I only get 9mpg so I was think that possibly my converter could be clogged? I guess i have two questions.
1: Is it possible that the converter could be causing my bad mpg?
2: Does that pinging sound mean anything or is it normal?

Ive never heard of a cat making noise but a bad cat will absolutely ruin your mileage.

I'll take a video of it later an post it so you guy can hear it. It maty be normal, but it just sounds strange to me an I'm not 100% that's where it's coming from, but when I put my head under there it sounds like its coming from that.
