Just today I got a P0420 code. Something to do with catalyst system low effeciency. Can someone help before I take it to repair shop and get ripped off.
Also, my daytime running lights are not on. Can someone tell me how to enable the DRLs or how to check to see if they are malfunctioning.
Did ja check and see if the bulbs are blown?? Or possibly the fuses since I noticed a previous post from yourself stating that you had no rear brake lights?? God Bless, Joe
Depending on your mileage and fuel used your convertor maybe shot, they do go over time. :(
Ja I replaced mine got an aftermarket one,(Eastern Converter), for $235 off of ebay and cost me $100 for installation at me local shop. Now I use nuttin but premium fuel. God Bless, Joe

joee5...I hope you mean premium branded fuel and not premium grade...don't waste your money on that...unless you have done something to your motor our L31 V8 can't do anything with it...be safe!
Heya Bill, Now you tell me,(j/k). Unfortunately I've been putting premium grade fuel in the whole time. Thanks for the 411. God Bless, Joe

I have over 260 K miles on it. Yes, I probably need to replace it. Is there such a thing as a universal converter, in which I can use on my escalade. Or is it a specific converter for my truck?

I don't know about universal but you should be able to get one at your local muffler shop and there are other companies (other than stock) that make 'em...good luck.
