Has anyone thought it maybe has popped a hose off?

yeah thats wat i was thinking.

i read on here that if it pops a hose off u can unplug the afm so it goes into limp mode and the car will actually idle. any1 else heard of that or is it bs?

ok guys, Had another play with it just then..

I put the stock BOV back on and check everywhere I could for any air/vacuum leaks but couldn't find anywhere I could possibly imagine one occurring..

After I reset the ECU by disconnecting the battery again (still not sure how I can tell if this works?) and started the car it did the same thing.

Originally it appears to idle fine until a few small pumps on the accelerator (of which it struggles to spool and revs very roughly) then it has trouble idling again??? after reving it a bit it then also starts to pump out black smoke again and shutters. I had a look in the bay while it was idling also and you can notice how much it shutters by looking at it (for some reason it appeared to me to be the turbo that was causing it). So I still think its the turbo that has shat itself but still hope ive missed something????

Does anyone know any good mechanics in the Geelong/Warrnambool area that actually knows what they are looking/talking at/about that may be able to solve my problem???

Cheers,

Dallas

black smoke is generally way too much fuel not dead turbo, another vote here for a popped hose or vaccuum leak. get someone who knows what they're looking at to check your hoses and pipes.

if you're around geelong, a workshop i've had good experience with for basic mech stuff is Dalton Auto-

Hey guys,

Just an update. I've booked my car into a decent mechanic finally to fix whatever problem I have (suspected vacuum leak I can not find). But just wondering what does it mean when I disconnect the AFM? I disconnected it and the idle started to change then stalled seconds later?

Cheer. Hopefully she'll be up and going soon :D

In the shop as we speak... Been told it was just a bad exhaust leak and all my gaskets had been burnt out and it was getting confused or something.. getting the new tune and all fixed up by start of next week, will let u all know what the solution was ;)

I'm having a slightly similar problem except my car is pretty much stock, apart from cat-back. My revs start to fluctuate between 100 - 1500 rpm in idle, but only after a bit of driving (when car is warm). If I try to drive when this problem kicks in, I can feel the car pull back timing hard which means no power from the engine.

I've tested for vacuum leaks and cleaned AFM but still problem exists. Going to clean AAC valve this wkend but i'll be waiting to hear what was wrong with your line once it gets out of the shop.

be aware there is nothing to tune on the std ecu... so dont pay for one. A tune on a std ecu is a reset... ie removed battery terminals for more than 30 secs... then doing the timing.

Changed plans.. picking up on wednesday.. will let all know what the result is then..

As for the tune I actually purchased a PFC (as well as other bolt on parts) so it can all be done properly and actually worth while..

I also thought that an exhaust leak wouldnt cause this but thats what im currently being told. I believe the leak was from the manifold gasket but all the bolts on the exhaust had come loose apparently??

Will know alot more when I actually go to pick her up so will update then..

Cheers

i doubt all these problems would be caused because of an exhaust leak...

yeah you could pull the whole exhaust off and all that would happen is it would run a bit more boost and run a bit richer and more retarded timing.

Got her back wednesday

Final verdict that it was the terrible exhaust leak from the manifold gasket that was the major cause. Had this all fixed up with a new dump and front pipe inserted aswell.

Also had, full tune, FMIC, BOV, manual boost controller, repaired turbo water hose, heat wrapped, flush n bleed of coolant system also done..

After the tune she puts out 222.6rwkw (on 14psi) which I very happy with as I was only hoping to break 200.. runs very smooth now and has a lot more aggression ;)

    • Hi, is the HKS  Tower Bar still available ? negotiable ? 🤔
    • From there, it is really just test and assemble. Plug the adapter cables from the unit into the back of the screen, then the other side to the car harness. Don't forget all the other plugs too! Run the cables behind the unit and screw it back into place (4 screws) and you should now have 3 cables to run from the top screen to the android unit. I ran them along the DS of the other AV units in the gap between their backets and the console, and used some corrugated tubing on the sharp edges of the bracket so the wires were safe. Plug the centre console and lower screen in temporarily and turn the car to ACC, the AV should fire up as normal. Hold the back button for 3 sec and Android should appear on the top screen. You need to set the input to Aux for audio (more on that later). I put the unit under the AC duct in the centre console, with the wifi antenna on top of the AC duct near the shifter, the bluetooth antenna on the AC duct under the centre console The GPS unit on top of the DS to AC duct; they all seem to work OK there are are out of the way. Neat cable routing is a pain. For the drive recorder I mounted it near the rear view mirror and run the cable in the headlining, across the a pillar and then down the inside of the a pillar seal to the DS lower dash. From there it goes across and to one USB input for the unit. The second USB input is attached to the ECUtec OBD dongle and the 3rd goes to the USB bulkhead connected I added in the centre console. This is how the centre console looks "tidied" up Note I didn't install the provided speaker, didn't use the 2.5mm IPod in line or the piggyback loom for the Ipod or change any DIP switches; they seem to only be required if you need to use the Ipod input rather than the AUX input. That's it, install done, I'll follow up with a separate post on how the unit works, but in summary it retains all factory functions and inputs (so I still use my phone to the car for calls), reverse still works like factory etc.
    • Place the new daughterboard in the case and mount it using the 3 small black rivets provided, and reconnect the 3 factory ribbon cables to the new board Then, use the 3 piggyback cables from the daughterboard into the factory board on top (there are stand offs in the case to keep them apart. and remember to reconnect the antenna and rear cover fan wires. 1 screw to hold the motherboard in place. Before closing the case, make a hole in the sticker covering a hole in the case and run the cable for the android unit into the plug there. The video forgot this step, so did I, so will you probably. Then redo the 4 screws on back, 2 each top and bottom, 3 each side and put the 2 brackets back on.....all ready to go and not that tricky really.      
    • Onto the android unit. You need to remove the top screen because there is a daughterboard to put inside the case. Each side vent pops out from clips; start at the bottom and carefully remove upwards (use a trim remover tool to avoid breaking anything). Then the lower screen and controls come out, 4 screws, a couple of clips (including 3 flimsy ones at the top) and 3 plugs on the rear. Then the upper screen, 4 screws and a bunch of plugs and she is out. From there, remove the mounting brackets (2 screws each), 4 screws on the rear, 2 screws top and bottom and 3 screws holding in the small plates on each side. When you remove the back cover (tight fit), watch out for the power cable for the fan, I removed it so I could put the back aside. The mainboard is held in by 1 screw in the middle, 1 aerial at the top and 3 ribbon cables. If you've ever done any laptop stuff the ribbon cables are OK to work with, just pop up the retainer and they slide out. If you are not familiar just grab a 12 year old from an iphone factory, they will know how it works The case should now look like this:
    • Switching the console was tricky. First there were 6 screws to remove, and also the little adapter loom and its screws had to come out. Also don't forget to remove the 2 screws holding the central locking receiver. Then there are 4 clips on either side....these were very tight in this case and needed careful persuading with a long flat screw driver....some force required but not enough to break them...this was probably the fiddliest part of the whole job. In my case I needed both the wiring loom and the central locking receiver module to swap across to the new one. That was it for the console, so "assembly is the reverse of disassembly"
