this. cheapest first. and if its clogged it will cause all of what you said. my fb rx7 would run fine under half throttle, but as soon as i went half throttle to WOT, it fell on its face. to the point where it wouldnt even run. replaced a bunch of shit and i still couldnt figure it out. turned out, it was the fuel filter the entire time.
always replace the cheapest stuff first.
