Default LTs installed, Problem. Help!

I had LTs+ORY installed about a month ago, everything was fine until today. The "Service Engine Soon" light came on . Out of the blue. I have O2 simms, so that can't be it, could it? Can anybody help me?

Get your car scanned for the code, it may not have anything to do with the LT install your car has so many sensors,etc. reporting to it that the light could be set off by any componet of your car.

If there is an Autozone in your area, im pretty sure they have a scan tool, and the one where i live they do it for free. Or you can just take it to a local GM dealer.

Question

Did you remove EGR and/or AIR by any chance?
Block off plates come loose/leaking maybe?

murrays or autozone will lend you their scanner for free, just go there and do it in the parking lot.

I lost a front O2 sensor not long after the install of my LTs...I was told that sometimes the install of LTs can cause a temporary rich condition while the computer adjusts to the increased air flow, which could foul an O2 sensor...don't know if this is accurate or even possible, but that's what I was told...

they could have been contaminated upon install.
