Am i the only person whose catalytic converter has gone to sh%* twice? My service engine light was off after changing it last time but now it''s on again. Oxygen sensor?

 

OK ...


Which vehicle do you own, and what mileage on it, and what codes are being displayed ??

 

Yeah, what he said.

 

2001 L200
140,000 miles

 

Great - sorta ....


Wenow know the year, make, mileage, and model.


Still need the service codes that the car is reporting ....

 

I recently had my cat replace on my L200. It took two dealer trips and alot of online searching before they determined the cat was the problem. My 02 L200 has only 50k on it. The dealer said the ignition coil and module had to also be replaced, as they were causing a rich condition which is what flooded the cat. It''s possible your motor was still running very rich after you replaced the first one. Keep in mind this is only a guess based on personal experience......hope it helps.

 

AorZack is right - and the service codes would show that ...
