so we swapped out the knock module and that didnt fix it. we fixed a broke wire on the knock sensor and that cleared the code.

so what is it doing? when the car is cold, it has a slight mis to it. as the car starts to warm up it get worse, then when you bring it up to around 2500 rpms it will start to "pop" out of the exhaust and cut out. seems to only be on the drivers side pipe. when under load, when you put it in gear when its up to temp it will stumble and die. i am starting to think that the coil or icm maybe going out. since when it warms up it gets worse. i would not thing the opti would cause this.

there are no codes on it now.

you opinions would be great.
