Drove my car today, and noticed that when I go about 80% throttle, it will losse power for about 1000 rpm, then it kicks back in, almost like timing is being severely pulled. Happened above 3500... 1 time happened from 4~5000 rpm, another time 4500~5500 rpm. Any ideas? I have no codes being thrown, and driving normally it drives great. Anything above 70-80% throttle and she looses power...
