Default LT1 DTC Codes - Symptoms of Other Issues?

Hi All:

The car is pushing the below codes although the check engine light is not showing on the dash. I have a 96 with a 383, longtubes, CSR EWP, no cats, etc. etc...

Was wondering if these codes are signs of other issues or potiential issues to come. I read the definitions that were available on gearchatter (which is a resource btw) but really made little sence to me.

DTC P0134 HO2S Circuit Insufficient Activity Bank 1 Sensor 1
DTC P0154 HO2S Circuit Insufficient Activity Bank 2 Sensor 1
DTC P0443 Evaporative Emission (EVAP) Purge Solenoid Control Circuit
DTC 1661 ?? (no definition on gearchatter)

Any additional info you guys can help with would be great.

Thx

Jeremy

Was doing searchs, after searchs and dug up my own old thread so why not revive it!

Im researching what o2s to get and a few questions have come up (getting Delcos):

Ive read that corvette o2s seem to be a popular choice? Are these good for mod'ed cars or is an o2 an o2 no matter what?

I have no cats, so Im assuming I need the front o2s?

BTW...my car runs stocker like ETs or worst...sad..sad...thinking the o2s are killing it.

Also, I have extensions, the plug ends where the wires go into the connector are exposed, when it rains the car runs horrible...feels about like 3 cylinders firing. How are you guys wrapping these to keep moisture out? I bought the car this way and just trying to clean up someones half a$$ job
