I was driving just before and my car was not runing right...

It would hesitate to accelerate and a funny sound would come from the exhaust (bwaaaa) almost like it wasn't firing or something, the boost stayed normal?

This isnt the first time, It doesn't miss fire/pop or anything, it just took allot longer to rev out??

i would check fuel pressure and filter make sure it actually getting fuel there, and when my air flow meter plug was a bit lose i would get the same problem, with inacurate readings from your flow meter this would cause the car to either not run or run really rich. but from the sounds of what you have discribe that so sound like your cat even though it is fine. verry odd.

Mate its about time you took the car to a decent workshop to get it checked out.

All your threads seem to point to one thing - you car has issues, they need a professional to look into.

mate, i have been to four mechanics, two of them rep tuners, two of them searched for the problem with obviosly no success, that cost me $400, $200 each.

so im trying to find the problem myself...

when my car had issues with the stock coils, it sounded like a wrx, ie dropped a cylinder. That very distinctive boxer style rumble.

could be coils i suppose.

have had you compression/leak down tests down? checked timing belt? etc...

Mate you can't even describe the problem in accurate detail, troubleshoot parts or anything.

Im not having a go at you, but honestly people can keep throwing suggestions at you for the next month and you'll still not get it fixed.

There are decent workshops in each state for this type of thing. Failing one there is always a 2nd choice.

Now i find it hard to believe you've been too two reputable workshops - not tuners - workshops. This is a mechanical issue unrelated to the cars tune.

Just a quick one and no i'm not being a smart ass but check there isn't something preventing you from getting wide open throttle, like a car mat or the like? has happened before and not getting 100% throttle opening could be what you're experiencing. Good luck hope you figure it out.

      Even more fun, leave all the ADAS stuff plugged in, but in different locations, hopefully avoid any codes!   And honestly, all these new cars with their weird electronics. Pull all the electronics out Duncan, and just shove an aftermarket ECU and if needed a trans controller in, along with a PDM. Make it run basic but race car styled!

      To follow up a question from earlier too since I had the front bar off again (fking!) This is what is between the bumper and the drivers side wheel And this is the navigator side, only one thing but its a biggy! So basically....no putting coolers in the wheel arches without a lot of moving other stuff. Assuming I move to properly race prepping this car I'll take that job on and see how the computers respond to removing a whole bunch of ADAS modules

      So I prepped the car for another track day on Wednesday (will be interesting to see coolant temps post flushing out and the larger reservoir, with a forecast of 3-14 being 20o cooler than last time I took it out). Couple of things to mention; since I am just driving the car and not taking a support vehicle, I took the rear seats out and just loaded the back up Team Trackday style. Look at all that space! To cover off removing the rear seat....it is weird (note the hybrid is probably different because it wouldn't have folding rear seats) Basically, you remove the lower seat base, very similar to a r series but it is a clip that pulls forward to release the base rather than it being bolted down. Easy Then, you need to remove the side section of the rear seat on each side. There is a 14mm head nut at the bottom of the side piece, the it slides upwards off a hook at the top to release; you also need to unhook the seatbelt from the loop at the top. Then the centre piece is weird. You need to release/fold the seats forward with the tab in the boot on each side From there, there are 2,x12mm headed bolts holding the rear of each seat to the folding bracket, under the trim between the rear seat and the boot (4x christmas tree clips there, they suck). The seat is out but you can see where the bolts attach to the bracket

      As discussed in the previous post, the bushes in the 110 needed replacing. I took this opportunity to replace the castor bushes, the front lower control arm, lower the car and get the alignment dialled in with new tyres. I took it down to Alignment Motorsports on the GC to get this work done and also get more out of the Shockworks as I felt like I wasn't getting the full use out of them.  To cut a very long story short, it ended up being the case the passenger side castor arm wouldn't accept the brand new bush as the sleeve had worn badly enough to the point you could push the new bush in by hand and completely through. Trying a pair of TRD bushes didn't fix the issue either (I had originally gone with Hardrace bushes). We needed to urgently source another castor arm, and thankfully this was sourced and the guys at the shop worked on my car until 7pm on a Saturday to get everything done. The car rides a lot nicer now with the suspension dialled in properly. Lowered the car a little as well to suit the lower profile front tyres, and just bring the car down generally. Eternally thankful for the guys down at the shop to get the car sorted, we both pulled big favours from our contacts to get it done on the Saturday.  Also plugged in the new Stedi foglights into the S15, and even from a quick test in the garage I'm keen to see how they look out on the road. I had some concerns about the length of the LED body and whether it'd fit in the foglight housing but it's fine.  I've got a small window coming up next month where I'll likely get a little paint work done on the 110 to remove the rear wing, add a boot wing and roof wing, get the side skirt fixed up and colour match the little panel on the tail lights so that I can install some badges that I've kept in storage. I'm also tempted to put in a new pair of headlights on the 110.  Until then, here's some more pictures from Easter this year.

      I would put a fuel pressure gauge between the filter and the fuel rail, see if it's maintaining good fuel pressure at idle going up to the point when it stalls. Do you see any strange behavior in commanded fuel leading up to the point when it stalls? You might have to start going through the service manual and doing a long list of sensor tests if it's not the fuel system for whatever reason.
