i have the EXACT same problem. The first couple of gears (up to 60ish mph) the rpms work fine. Going beyond 60mph is labor intensive. I have to WOT the car to jerk out of the 2.5k syndrome.
I think both of my rear 02 sensors on b1 and b2 have crapped out. I already replaced one of them already (P0159) cuz at the time i thought only 1 was messed up...but now the CEL is back on again.
I'm planning on going to Autozone today to see what it is....
FAUCK man! i really hate this car now

Mu was just over, we swapped mafs and his car ran like a champ (obx headers btw did make a noticable difference in the rpm and speed range, speaking from the difference of mine). It was his MAF thread closed
