Fj62 Cat issue

[westy]

I have a '89FJ62 and my one catalytic converter is rattling like a tin can full of marbles. No real loss of power but annoying as hell. Cat gone bad? Any suggestions for non-OEM replacements?

Thanks,

Can't help you with the replacement but the rattling is the internal guts. Was likely overheated and had a meltdown. Could be because it was run out of gas or could be a persistent lean condition. Better check that you are not lean as this will melt down a new cat and also can cause other engine damage of course.

Thanks Eric, It is the CAT. I will be checking for lean condition.

could also just be age. any good muffler shop can replace with an aftermarket 1 that will fit in there.

New CAT installed and she's running like a top. That old CAT was really making her sluggish.
