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

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

thanks guys,

Din

sounds like a fuel pressure issue - what you describe is the same as when you get fuel surge or run out of fuel

didn't even think of that! could be one of the reasons!

i was also thinking, maybe its the coil packs in the early stages of dying? i have had them for a long time and since they changed the spark plugs, they are making the coil packs work a lot harder and it only happend at constant high revs when the car had warmed up. hmmm.

could try regapping them to 0.8mm

but if the engine is revving higher, but no acceleration - sounds like fuel issue

      You’ll be very upset when you bust that too not to mention the gearing totally sucks. Don’t do it.

      Is the panel filter one that is oiled? Have you ever cleaned or touched the AFM?

      So.... the K&N air box thingo was too big, ended up gifting it to a mate, well, by gifting it he actually supplied food and beer at the pub,  which was nice, as it will not sit on a shelf in the garage for the next 10 years I did trim up some of the existing stuff to neaten it all up and gave it some wrinkle paint, unfortunately it currently has a used and abused mish mash of different types of hose clamps, 4 big fat T bolt type (shit), and a few normal clamps of vairing sizes and brands, but..... only until the 6 constant tension black worm clamps that I ordered from EFI solutions turn up next week Currently the current hose clamps are triggering me hard, LOL Is this the final version, probably not, I really want just 2 silicone pieces, a straight bit of silicone from the filter to the MAF is easy and will happen as soon as I head into Just Jap tomorrow, the problematic part is a 30° silicone bend from the MAF to the TB that I can connect the engine breather from the head, I found that there are bulk head fittings for boat bilge pumps that should work, but until I can get a 30° silicone bend the alloy pipe, and the 11ty thousand hose clamps, are there for the foreseeable future 4 hose clamps are golden, 6 are grudgingly acceptable, the 8 currently holding it all together is just taking the piss    I've also ordered 60 more retaining wall blocks for the front yard, I mis-gonculated the height that was required to get above the base of the Photinia's (red robin's) that are the hedge behind the front fence, currently it is 2 blocks high, and about 1/2 a block short, so going 3 blocks high will be above the base of the red robin's, and allow some room for mulch

      It is the stock air box with the panel filter. Everything else is stock except the exhaust at this point, as I also went back to the cleaned 270cc injectors. I will check the RPM when the IACV is unplugged and report back.

      As MBS suggested if this is happening when the engine is cold you're going to want to remove the intake air regulator and verify resistance + that the shutter is physically opening and closing. At -20C should be fully open, 20C half open, over 60C fully closed. At 20C should be 70-80 ohms. For AAC valve testing using a Consult cable see if you can raise and lower the idle by commanding more or less AAC duty cycle. Hopefully it's pretty linear as well, shouldn't be like 30% AAC valve is barely idling and 40% is 1500 rpm.
