88k And Just Got My First Check Engine Light

[jeepandlexus]

Well, my suspictions were confirmed. Power and mileage were down and there is a pretty good leak coming from under the Lex. I just got my first Check Engine Light....... So funny how the Lex became my car after it got hit LOL......anyway, I have a code reader so it was no big deal. It gave me an inefficient catalyst code. I am assuming the CAT is shot. Where are u guys shopping for cats besides ebay?

Most likely the cat isnt shot it is the down flow O2 sensor it depends what bank it is. In order to determin if it is the cat use a rubber mallet and tap the cat if there is nothing rattling around than it is the sensor
