Engine stutter at high r's and at wot
Got a weird problem, car runs great with general driving, but when I lay into her she runs good for a bit then baam it seems like a severe misfire (bad coil or fuel?)but no codes are thrown, only codes is the tps. It only stutters at the high end and I can let off and do it again and sometimes it won't miss a beat. I've done about everything I can think of and I'm stumped

Maybe it's tagging the rev limiter? If it's an A4 it will typically shift slightly after the set point as it takes the trans a few milliseconds to actually shift. Mine does this once in a while, particularly if it's spinning the tires when it shifts because the rpm's are building faster than they would be if it wasn't spinning.

Could be your valve springs. Mine had a stutter that started at 5000rpm and lasted till about 5500 then pulled fine until the rev limiter. After I changed the springs out it was gone. Also the motor will make a funny sound when the stutter is happening.
