I recently picked up a mk5 gti with 98,500. On the way home, it threw a CEL, i didnt think much of it since the car was running fine. A few days later i was coming back home from somewhere and decided i havent tried to test its power or speed. So i decided i'd give it more gas slowly until i was to the floor. I was in 6th going highway speeds. Rpm's slowly crept up until, if i had to guess, 3.5-4.5k rpm when i got a complete boost and fuel cut. I let off immediately and also the engine didnt stop running or stall, i just got a massive cut in power. I gave it a little gas after that and it sputtered for another half mile or so and then acted fine. It starts right up when its cold and has a little trouble when its hot or been warmed up. Also drives perfectly under normal driving circumstances. Car throws codes p2293 fuel pressure regulator 2 performance and p2181 cooling system performance. Im thinking of starting with replacing the fuel filter under the rear passenger side, HPFP and cam follower. Just looking for some opinions or ideas.
