Losing Power On Acceleration

[dineth]

hey guys! just got my car serviced and found an issue when driving back on the freeway, i was going around 110 km/h and all of a sudden during acceleration, the car started to lose power and saw the speedo going the opposite way, this lasted for about 2-3 secs! was wondering what this might be? Why would the engine while accelerating bog down and loose power then regain all the power at once? its idle's and runs fine normally and this is the first time its ever happend. Its a R33 gts-t.

any feedback welcomed!

hey mate! i couple of people have said its the air flow meter, but its been working fine before i got my car serviced. What they did stuff up was that they accidently damaged the o2 sensor on the downpipe (by leaving it on top of the turbo and it melted) and they replaced it, but maybe they did a shoddy job? does anyone know if the O2 sensor on the down pipe is connected to the AFM in anyway?

02 sensor is only used on cruise for closed loop AFAIK

Does this happen only on high speed cruising? It could also be the fuel pressure regulator not supplying sufficient fuel to the engine when you open the throttle.

hey mate, sorry to sound like a dumbass, but what does that mean exactly?

hey mate, i drove it all last night and it didnt happen again, but the car feels very different to normal, maybe its running really rich? it seems to be less responsive than it used to be and car sounds a lot more dull/quiet than what i remember it to sound on idle?

for fuel efficiency at cruise, not used when giving it any
