I've got maybe 1100mi on this setup. There is a slight miss at cruising throttle positions where the car will fall on its face and then cut right back in again making the car jerk. Its slightly anoying but this is the only condition in which it occurs. It idles fine and will go away if you push the throttle down. It also will not happen during the first couple of minutes of driving, then it becomes noticeable. Its got me thinking that the problem is occurring during closed loop. Does this sound like a problem with the O2 sensors?. Perhaps the paper collector gaskets are leaking or the sensors are bad. I'm using O2 extenders that run pretty close to the hot headers. Thanks for opinions in advance. Just started posting again......good to be back.
