How can you tell when your cat converter is FUBARred ?
After a five minute drive down the road on a cool night tonight, mine glows orange hot fom the centre of the cat con. and then for another metre down the pipe towards the muffler...
So orange hot I thought some Sunlong guy had fitted some neons to it while I was filling the tank....the garage floor was glowing better than a Paris hotel fire.....
Exhaust has some rank burning toxic metal smell and the engine does not rev out cleanly.
I was running very rich for a few days....does it take much raw fuel in the cat to kill it ?
Final question, for tuning this car to correct A/F ratio's, should I just knock the guts out of this cat and refit it, or spend the dosh to replace it with new one ?
