hey everyone i wasn't 100% sure where to post this but everyone on hear are very good and im from vic also so hear it goes: a few days ago i had a little accident and have a huge dent in the bonnet so im looking for a new one at the moment. just today my dad took the car out and came home saying the engine light is on so i go to start it up and it was really rough the whole car was shaking, it felt like a had a huge v8 that wasnt really running well. so i pulled it in and quickly shut it off. now my problem is would anyone have any ideas what it could be because tomorrow is a public holiday and i got to get to work on wednesday so i was hoping it could be maybe a lose plug that would do it or would it be much worse :blink: .

thanks for replying. ok i have a r34 workshop manual it says how to do a diagnostics check but it really makes no sence to me it says to put the keys in to on but dont start the engine and then to put some wires into something to activate it. i tested my car today and checked all the plugs and stuff and they are fine i started it up and it sounded fine but then the whole car starts vibrating really badly and a very strong smell of fuel which could be normal cause it hadnt been started up for a day and a half. its killing me cause im too scared to drive it somewhere in case it is serious or if its just coilpacks.

im from sunbury but i think most people live on the other side of melbourne. it felt like the more the revs slowly dropped the more vibration throughout the entire car. im still thinking coilpacks from what i have read but not 100% sure.

ok guys hear is an update. i just started my car this morning and there was no engine light and it was fine, after a bit i revved it a little then revved it to about 5000 and it dropped normally but then the light came on again but still seemed to idle this time ok without the bad vibration but it did smell really bad of fuel i dont know if this is normal for starting it up in the morning but it was bad.

thanks for your answer i had a feeling it might be but it threw me off that it would vibrate badly and run roughly but then again i suppose they could do that too. plus my car was driving on that really hot day on monday so that could have cooked them as well.

the vibration is the fact that one or more coils/cylinders is not firing at all.....to find out which ones are the culprits let the car idle(when its playing up) and take the injector wires off one by one.....you will find that there will be ones that eitheir make the car stall(the good ones) and one's that dont make a diffrence (the evil ones)

Hey... I've also got a R34 and i had the same problem as you... engine light, SLIP and TCS OFF light would all come on and the car would be shaking.. sometimes the shaking would go away and the lights would stay on.. very very intermittant... and yes it was the coil packs

Now got some splitfires in there and runs perfect :O

im not stupid i know how to look after my car. i have only had it for about 3 months and it had a full service before i picked it up, so im pretty sure its fine, and i do check my oil frequently and coolant and all the rest.

    • 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"
