Yesterday, my truck started idling extremely rough and smelled odd, took it to Ford house and they diagnosed as injector problem (2005 5.4). Anyways, a few years ago, I had high flow cats installed. I ordered the Magnaflow 94106 pn (If I recall correctly) and the man at the shop I was then using told me they wouldn't work because of the O2 bungs..whatever..he ordered a new pair and covered the fee.
** Now, I need to replace one of these unknown brand High flow converters because the unburned fuel from the leaky injector ruined it.
What would you do? Call the shop that put on the new converters and ask what kind they normally order? Just curious.

Also, how long could a man wait to replace the cat? I had only run the truck for maybe 10 minutes with the injector problem. 6 months maybe?

Thanks a ton,
Will

 

I wouldn't run it for a week with a burnt cat, but that's just me. Buy a new 94106 cat from performancepeddler.com for less than $50, then get it welded on IMMEDIATELY.

 

Will it matter much if I run two different kinds of converters? I have no idea what brand these two are but they look just like the pictures I've seen of Maggie 94106's..

 

Not sure. Why don't you buy the 94106's on your own and have him weld bungs in after the cats?

 

So I would just take in a 94106 converter and tell the mechanic to cut and replace the cat, weld in a bung after the cat and install a new O2 sensor? Just making sure
Thanks,
Will

 

Yes, but have them weld the O2's as close to the cat body as possible, like on the exit pipe on each individual unit. I've been hearing of people getting CEL's because their O2's were welded in too far back.

 

^ But we always say "as close as possible"...

 

I know, but some people's definition of "as close as possible" might vary.

 

Does that injector problem only happen to 05 f150's??? I have an 06 and have a bad cat and it smells kinda strange too when running.

 

I thought the Ford letter indicates that they will fix the additional damage caused by the bad injector?

Regards!
