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
