Your plugs will more than likely to be covered in junk by now.... this will cause the increase severity of the misfire problem.

You can learn a lot from pulling the plugs and 'reading' them (although it may be to late now). I'd suggest you pull them asap and post up photo's (keep them in order).

Replace the plugs and at least you will be able to drive it again for a few km's.

Honestly I can't see your O2 sensor being the problem (just unplug it if you aren't sure), fuel filter is a good service item, but unlikely to stop you from miss firing. A wide band is only going to help if the mixtures are actually getting burnt.... as soon as it misses, you will just get rich afr's off the scale-

I'd be buying/borrowing a new coil pack loom and a known good ignition module before buying another set of coil packs.

If you still have issues, pull the injectors and get them cleaned/flow tested.

after that... take it to a mechanic.

I had similar issues with my R33 s2.

I had checked and resoldered the pins in the afm for the plug, made no difference, but it was actually dry joints on the afm board itself. Fixed those up and she's been apples.

Also, is the z32 afm genuine? There are copies floating around

Xrated, it's a s2 motor so the ignitor is built into the coil pack. Unplugging the o2 sensor doesn't make any difference atm so I'm replacing it anyway.

Cef33y, I'll see if anyone in town has a z32 afm I can borrow. I double checked and mine is genuine.

I had the same thing happen to my Stag. I was sitting at the lights one day and it started running real rough. By the time I got home the car was real rough. I turned it off and it wouldn't start again. Checked this, that and the other, no good. Pulled the plugs and they looked OK, although a touch dirty. Changed them and bammo, car fine again.

Jam a multimeter in your car and see if your voltage drops as there's load on your motor or if you can just log it from your ecu.

I had a shit house misfire problem too, turns out was my stock alternator playing up. On idle, it would show up 13.8V but as soon as you increase the RPM it would drop to around 12.2V. Replaced it with a brand new Circuit Sports one and misfire gone!

New coil packs, new 02 sensor, new tps, new plugs. Starts, Idles and drives fine and smooth. As soon as you try and boost it, feels doughy as and misses and doesn't make any power. Still yet to fit a new fuel filter.

Still have to find another afm to try yet

Any workshops in Alice Springs NT you could recommend?

Its something that isn't affecting just 1 cylinder as the last lot of plugs were all sooted up. I just feel like I've gone over everything twice without any luck.

    • 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.
