My Cat converter has given me the rotten egg smell after runnin WOT.. on a few occassions.. and I"m not accelarating right.. it seems to lag till top 1K RPM ( compared to normal ).. so I"m guessing the current cat is clogged.. but I had it replaced 2 years ago.. just wondering what would cause it to foul so quick?

Only thing I can think of is a rich setting.

I"m gettin a scan tool soon to get the reading from the 02 to see if it registers if I'm runnin rich or lean.. ( well noobie to scan tool so I"ll have to find out what the norm would be and compare ) and I have no CES ( which would occur if the 02 sensor is dead )

So other then replacing the 02 sensor also.. what else could foul up a Cat converter so quick?

I"m planning gettin a hi flo cat (carsound/magnaflow), but I don't want to keep replacing cat converter every 2 years.

Been a while Drifter...

Just an O2

On the high flow..get a direct fit or you'll have trouble getting it welded on.

yea.. sure has been a while..

Tamara'* 95 is on the last leg... tryin to save it till we get her another bonnie ( this summer )

so just 02 sensor?? and only cause of rich settings that'* usually causing the cat to do so quick??

P.*. Hey Boost

the guy that did mine said he would rather do the universal. Did a quality job on mine in no time. Used the old factory flange (never unbolted it) Had to do it this way because nobody had the direct fit, even magnaflow. Was told it was 2 months out waiting for their production cycle.
