Revalation......Could 02 senors be at fault?

[MysticKeith50]

Ok...idling problem, stalling....yada yadayada. I contacted JMS about the SCT chip and they told me make sure i reset base idle, tps, iac, etc. One thing I just never put a second thought to was the o2 sensors. They told me the sensors must be in perfect working order. They said if you ever blown a head gasket for example your o2's are shot. (which made me remeber) When we did the swap, (especially on passenger side) when we took the heads off a descent amount of coolant went into my x-pipe (amazing shot, but it is true). When we started the car it smoked like a motha because of the coolant in the exhaust for about 5 minutes (locamotive style). Could this have destroyed my o2's and could this be a factor in all this . I do not have a cel on but . Also I went to Advanced Auto parts to get two just in case, and they said there were 2 types for our car...before and after cats...I got the before, because they are before on my x-pipe. Any feedback would be appreciated.

I changed mine because they had some miles on them. I also threw some high octane fuel in when i went to the track. My car never threw a code. Right after changing them, I felt the difference in power and throttle response.
