My 92 LS400 failed emissions. Bummer. I've taken it to a local mechanic (S. sub of Chicago) who is suggesting the following:
Injection cleaner - $130
ERG valve replacement (Engine light is lit) - never been changed - $210
Sludge (I'm guessing carbon deposits) removal from manifold - $300
All O2 sensors - 3 are bad - $700 (parts & labor)
Both Cat's - ($350 ea. aftermarket)
The car has 165k miles and runs great. I was considering having the cats and EGR valve replaced with removal of the carbon deposits from the manifold. I wanted to do the O2 sensors myself.
Does this seem right to the group for emissions work?
Emission results:
HC (GPM) - 1.36
CO (GPM) - 25.9
CO2 (GPM) - 451.5
NO (GPM) - N/A
Need your help! Thanks

Here's where you can get some O2 sensors http://oxygensensors.com, and if you install them yourself you'll save a lot of money. I haven't yet, but will be ordering from that site sometime soon. They sell a universal one that works fine I've been told, you just need to splice the wires. I don't know about the other stuff on your list.
