im having misfires with my FI kit as well.The misfire with me occurs at heavy acceleration. Gas gets cut off as well. Recently my car died on the freeway lol. Sebastian is thinking fuel pump related. Car is in the shop at the moment, trying to get everything solved. Ill keep you updated.

Please do. I ordered a new upstream a/f sensor, but I'm not so sure that's the issue. I did a bunch of data logging, and it looks like the o2 sensor voltages are alive, so I doubt they are dead. One thing that is interesting is my Camshaft Adv Sensor in Bank 2 is stuck at -128. I'm looking into it further as I type this.
