wats up guys ive got a 2003 ecsb 4.8L and my cats plugged up along time ago and i just gutted them instead of spending alot on new cats but its come down to inspection time and i was wondering if neone knew of any one selling 02 simulators for that truck. thanx

 

one of the sponsors should have them but i don't know if sims will help you pass if your state uses a sniffer

 

my state jsut used the obdII scan and my caspers did just fine

p/n104036 or p/n 0182-104036

they are both on the box i dunno what for (these are from my 99)

check ls1tech about the differences i know they wont adapt to the ls1 styles diff plugs mine were black ls1's are grey?

you can buy some from all sorts of places new for about 100$ cheaper used im sure

 

you can also put the money toward a tune and delete the rear O2's. It will cost more than the sims but you will also have alot more fun with it.

 

exactly what I was thinking. get it tuned and just delete them
