A few times a day I will be driving down the road and the car will start chugging and shuddering. And then power will start to come back and then it hooks up.
My friend and I believe that it is because the o2 sensor is going bad and making the car run rich which in return is fowling the plugs out. Does this sound correct? If not what could it be? I am going to pull the plugs tomorrow and see what they look like.
Thanks.

With a few easy checks we will narrow this down for. it can be vaf, vacuum leak, bap, iac, tps. is it during throttle changes while driving? when hard accelloration or right after lifting? have a vac/boost gauge? is it when coming to a stop/coasting?
iac-coast/stop
vac/boost gauges-vac leak.
tps-throttle changes
vam also falls into throttle changes, keep load consistent and accelerate at an na pace and you will bust the vam/tps issue. i have a similar issue, think its the bap because its running ok when its hot inside the engine bay during traffic in arizona. but at night runs like ass bc its lean as ****. bap fails and the ecm sees wrong signal and miss calculates.

Well I went through and check the spark plugs and they were white.
I clean them up and put them back in the car. All the plug wires I took off broke and look'd like they were really old. So I put the 4 of the 6 stock wires from my Grand Prix on it and it seems like it has taken care of the problem so far. We will see if anything comes back.
