First off, I have a 2003 Sentra SE-R Spec V.

I was going down the road today, shifted into 6th and the car started bucking under any sort of throttle input. I coasted into a gas station and the car was idleing really rough and wouldn't rev past 2500rpm. Anytime I touched the throttle, the idle would drop and the car would stumble really badly. I'm not getting any codes, I did throttle relearn twice to no avail. MAF tap test didn't change anything, I can hear the fuel pump priming and all injectors clicking. If you slowly put throttle input it will build rpms to 2500 at which point it sounds like a rev limiter, but any sort of quick inputs and the car will stall. Any ideas on where to start? I replaced the throttlebody maybe 500 miles ago with a reman from Oreilly's so that is my first idea. Only other things I can think of are the MAF and ECU.
