There arent any 02 sims availible for us . The older OBD2 sims arent compatible with the newer GM's .

P0420 (emissions system low efficiency)
P0141 (HO2S2 Heater system low voltage sensor 2 bank 1)
P0140 (HO2S2 Heater system inactivity sensor 2 bank 1)
P0036 (forget which one it is but I got this code a lot too)

Those are the code I got after removing the cat and rear O2 sensor.

I tried the spark plug antifoulers, and it didnt work at all. HPtuners is the best bet.

Question for the catless dp...

When the CEL is thrown... do you have to get it reset? Will it hurt anything if you dont get it reset? How much HP did you gain? Inspection?????

yeah is it ok to drive around with it, or does the computer adjust and pull timing or anything of the sort?

My understanding is that it just a "warning" and there isn't any adverse effects.

I wouldn't drive around with a cel for very long. Should you get a REAL cel you'll never know it.

very good point. i guess ill put it on see how it goes for a couple days and proceed further. i know there is a couple guys around here with HPtuners. but is there a way to just use HPtuners to get rid of that code and affect absolutely nothing else?

Yeah, just take your current tune, disable the cels your getting and re-flash your car. Nothing with change except the disabled codes.

ok so the "tuner" should be able to read the thrown code, go in and disable ONLY that particular code? no need to touch ANYTHING else?
