2001 F250 5.4 smells like burnt matches

[alaskanford]

Hello everyone, this is my first post, so hopefully I don't break any protocols, but here it goes. I have a 2001 F250 Super Duty with the Triton 5.4. It has been a good truck, has about 135,000 miles and does a lot of towing in the summer. I live in Alaska so it operates in some harsh winter weathers. I just had a tune up and all the coils changed a month ago.

My problem is it just started idling rough and it smells like a burnt match, even burns my nose. It is not a sulfur smell. I checked the battery for cracks and leaks, but the smell is not coming from there. I have never experienced this in any other vehicle, and am curious if anyone has any quick suggestions as to where to start.

First off, welcome to FTF!

Second, it sure sounds like a cat going bad.

I second that. I can recall a similar smell on my truck when the cats. were nearing the end of their life span...

Welcome! BTW

Thanks for the advice, sounds like a good place to start. I'll work on that this weekend and get back to you on how she's running.
