Default Possible fowled plugs?

I need you guys' advice,
I just installed my LT's and LM1, well I was driving the car for a couple weeks without my O2's hooked up cause I switched to Heated 94+ Sensors and had to make the harness and also wait for my sensors to come in. Well it was obvious that the car was running a lil rich from not having working sensors and the last few day I can smell some pretty raw fuel and it still runs ok but sometimes when I restart it after driving it awhile, it takes maybe a second longer to start and runs at a low 500 RPM at idle but only until I go and open it up down the highway and clear it out, it will come out of it.

So now i've came to the conclusion that I may have fowled the plugs from not running sensors for 2 weeks. Has anyone heard of this happening by chance?

Also, which plugs should I replace them with? I have Delcos in there now with probably 20K on them.

I you need pics of the plugs, I will get some tonight.

Yes, your plugs are more than likely fouled. if you can smell it running rich, it can foul them out in a couple miles. especially if you have larger injectors. run a tr55 its a great plug.
