Losing Power On Acceleration

[dineth]

Hey Guys, just got my car (r33 gts-t) recently serviced from a different service place to my normal place and they have done a pretty shitty job! anyways, i got the car back home and then it wouldnt start once it got warm and i could smell electrical wire burning, once i opend the bonnet, i saw what the issue was, the wire harness the connects to the oxygen sensor on the downpipe had come off a table tie and was sitting on top of the turbo and it had melted it nicey all the way through, anyway i called the service people, they came down and swapped the plug over, (however not an original R33 wire clip) and it all seems fine etc

So today was the first day i took it for a proper spin and it was all good until i hit the freeway, i was driving along fine for around 10 mins then and accelerated to around 120 and i felt like the engine just died and dropped power and even though i was holding onto throttle, the power was dropping, the strange thing was there was no stuttering or missing(which you would get with coil packs/spark plug issues) it just felt like i lifted off the power but i was still accelerating. it was really strange. I took the next exit and it was running fine after that, and was reving without any problems. This has never happend before and i was wondering what the issue could be? could be be related to a dodgy job on the repalcement oxy sensor? The service guys changed the spark plugs could this be a issue? i am a bit lost

what the service guys changed

engine oil

transmission oil (car is auto)

spark plugs (platinum)

most of the blets like fan belt etc

my theory is that its something to do with the o2 sensor and the ecu is not detecting the correct figures, so running the car rich by defualt, thoughts?

sorry about the long write up, but all feedback much appreciated so i can get to the bottom of it

thanks guys,

Din

its a weird one, has it done it again since?

might have just been a tempremental thing.

if you cant get it to do it again dont worry too much.

hey mate, ye it hasnt dont it again! i drove it heaps yesterday night and gave it a bit of a trashing, it seemed all fine, car still feels a bit strange though, as in seems, but the car still doesnt feel as quick as it used to be? maybe i might need to reset the ECU after reinstalling the sensor plug.
