Check your fuel pressure. Blockage in the return line will raise the pressure at the rail causing a rich mixture.
This happened to me twice. Turned out to be the return line hitting the bottom of the tank. I had to cut 1/4 inch of the return line. I also cut it at an angle so if it bottoms out again it won't completely plug the line.

Hmmmmm.... I'm in PA & I never ran a cat in the WRX and it was always "inspected" without it????
Hell the guy I sold it to still runs it without one???
you should really get to know your mechanic better.... its not like the cops even know what a catalytic converter looks like.....
If you want to be stealth and never get caught EVER just gut the cat out and reinstall.

|Fweaky||Like tlrrob1000 mentioned before the clogged cat is often caused by a rich condition. That could be due to an oxygen sensor. Some folks gut the cat once it clogs and reinstall it.|

|Vaultzz||I hope its something easy like the oxy sensor. The same thing happened to the cat that was on it when I bought it. the inside was molten|

what you are dealing with kind of sounds like a converter meltdown.

|hannahuffster||Just dont run one, take it on and off for inspection...|

|tlrrob1000||Could be a couple of things...tune up, running rich, passing oil so on and so fourth. Like schnutzy said do a tune up, sea foam it, then adjust the carb and then if you are using oil (burning oil) then rebuild it.|

when was the last time the jeep had a good tune up? try that first, maybe run some seafoam through it and all. you could always just leave off the cat while your trying to get it running again. no need it buying a new one if you know its gona get clogged up. just leave it off so you can get it running. see if there is something you can do to unclog ur current one, then slap it back on. do that till you can figure out exactly what the problem is. but i still say give it a good tune up, make sure its running 100%(well, as 100% as a 21 year old, multi hundred thousand mile engine can be.) even if that isnt the exact problem, i dont see it hurting anything.

|schnutzy||catalytic converters are over rated...|

Help Jeep won't run!
Well I never thought I'd be posting one of these threads
Anywho, I jerry rigged some flares (I'll post th pics in the "last person to post" thread) and decided to take it out for a spin. (this is after it was sitting for about a week)
It was idling rough like always but when I got it up to 30 mph it started sputtering like crazy, rpms all over the chart, stuff like that. I figured it was just a hicup so I kept going. then 30 feet down the road it got ok and started running right then it happened again and this time it died.
Long story short I got out and inspected everything and found the back 3" of my CAT was RED HOT.
My freaking cat is clogged again... now this happened before abd I replaced the CAT but I'm fearing that the engine may be ruining them.
So we finally get to my question. What would be causing the CAT to clog like this?
Thanks guys you rock!
