Ive only had my 97 R33 Gtst for about a year now and hasnt really been driven alot and never really that hard.

Recently i have been having problems with the engine cutting out while just crusing. This problem normally happens within the first half an hour of driving. I may just be crusing along at around 80-100kph and the engine will loose all power. So the car is still moving just slowing down because there is no engine power, I push down on the accelerator and nothing happens, sometimes if i give it a little pump on the accelerator the engine will start again. Normally when it happens i pull over. It it doesnt start again i just slow to a complete stop and try starting it again. It normally starts again after a little while. So i just let it idle for a bit.

I found a little kink in the hose that goes to my Greedy profec BII boost controller. Since i fixed that it hasnt the car hasnt played up. But sometimes it maybe a week or 2 inbetween times it f**ks up on me.

The car has never really felt that powerful either, sounds like its running fine but im not a mechanic just a backyard one. Always is backfireing and spluttering around

So if anyone has had similar problems or any advice, i need it now before i spend some money on an expert for maybe a small problem like a fuel filter which is next on my agenda to change.

How serious is this problem? Is it an easy fix (DIY?) And what exactly is a Power Transistor Unit?

the power transistor unit provides spark for your coil packs.

its an easy job to replace and a 2nd hand unit can be picked up cheaply, but they are prone to failure. better off getting a new series 2 unit, try nissan. but make sure the ptu is the problem first by swapping it with another one that someone might kindly lend you to see if it fixes the problem.

Since i have no idea about the PTU, where abouts is it located (R33 Series II GTSt)? Is there anyways to test if this actually is the problem ie. Visual Inspection, Testing Resistances or Continuity with Multimeter. Is it possible to clean it or any way of restoring/fixing the original one?

Its just hard to borrow someone elses since the fault may only occur once a week or whenever its pretty random. Ive seen one on ebay for $200, but still dont recognise this component from under the hood. Help would be much apreciated.

Has anyone else had faults with there PTU or Similar faults to this. Would changing the PTU also fix a real bad flat spot between 4-5k?

Sorry all i want is some answers before spending $200 or so on a PTU that i may not actually even need.

Cheers

having some simular issues. let me know how it turns out for you

Sounds more like a problem with the air flow meter

Mine did the same thing on the way to get petrol one night. started up again fine and managed to make it home.

The next day it started and died after a min or so. Borrowed a replacement and it ran fine.

a dying AFM could cause the misfire too if its not reading right.

Your one could just have a loose connection, theres a DIY thread to fix them. In my case it wasnt repairable.

or it could just need a good clean.

Check your spark plugs and your intercooler piping for any leaks too

i took a look at the diy thread you mentioned and opened up my maf and noticed that almost none of my connectors were touching properly. so Im assuming this was my issue so maybe it will be yours as well.

i plan on replacing mine with a z32 soon, but not until i run put on all the parts ive collected to need it. Right now i am still on stock injectors/turbo so I dont think I need the z32 maf just yet but once again thanks for pointing out that DIY I will post up if thats the issue.

    • Seat of the pants assessment of the new intake: The car is way less "doughy" when hitting the loud pedal, especially off idle when stopped or in traffic, I did use a cheapo lazer thermal thingo to measure the temp around where the pod filter got its air, it was between 55 - 60°C, in saying this the car was shut off and not moving, so the OEM intake pipe was not supplying any fresh air to where the pod was when the car was at least moving A weird bonus was induction noise on the throttle in the cabin increased a bit,  I was worried that I was actually going to lose some of that induction noise I love so much, outside though, when I got the daughter to do a WOT drive by pass for me, the induction noise has increased alot when on the throttle, not quite ITB doort, but well up there I'm extremely happy with the results and have been exploring the country roads in the region  As for house mods: 1.New front fence is up and is awesome, it really upgraded how the joint looks from the street, and the added security is nice 2. Electricians have replace some interior lights, and with more lighting in the garage, a few new motion detecting lights out the front above the garage, front room, and at the front door, which I have already found heaps helpful coming and going, also now has fancy pants CCTV all round the house The only hold point for power though is the solar and batteries due to supply issues, although this will happen over the next few weeks 3. I have done a heap of landscaping out the front and I'm almost ready to do a new small retaining wall with some nice blocks to replace the brick and cemented in rocks around the raised garden beds cemented in river stone "was the fashion at the time" the house was built. I currently have a pallet of retaining wall blocks and 2 bulka bags of 20mm blue metal to replace the wood chip that is in the raised garden beds around the house 4. I now have 3 big raised garden beds for out the back to grow some vegetables, about 70cm high, 200cm long and 100cm wide 5. My 2 compost bins are already pretty full with brown, green and kitchen waste from the landscaping I'vedone so far, but they will probably take a few months to break down, so anything else that gets chopped, trimmed, and kitchen waste will just start filling the base of the raised garden beds to about 30cm before I start throwing 40cm of good compost, and stuff, for the vegetables to grow in, I'll need a few ton of compost and soil, but the local supplier can sent me bulka bags of the stuff Basically the logs, wood chips and a few strategically placed rocks for drainage, will give the beds some good organic materials down low to break down over time, and they will hold moisture during the warmer months to save the water in my big arse water tank if we don't get alot of rain So, all in all, the car and house mods are going well, and I'm really enjoying being retired, I sleep in too 0700 and slowly plod around inside until I feel like actually doing anything, and only work in the yard for as long as want, which has actually been alot over the last few weeks,  although when you look at it, it seems that not a huge amount of work has been done,  until I look at the before I started the work pics Happy days and good times indeed 
    • hahaha yeah. Plan is to get side skirts and probably just rear pods. But going to do them one-by-one. I've got a set that I really like from RHDJapen, but that one isn't shipped to AU. So need to find someone who can get it for me
    • Here's an idea, answer the questions I asked you as they are trying to work out WHY the LSD will be binding up in a straight line.
    • You haven't driven many modern cars then have you? Most of them have sfa steering feel with their stupid electric bullshit steering systems.
