Hey all,

I recently followed the AAC clean tutorial and Air Reg clean tutorial on here and now i've run into some problems!

After completing both and putting everything back in the car i had high idle/reving.

Car was also shaking alot and when i took the car for a drive i had no power and car wouldn't go.

The idle issue has been fixed now but i still have the problem where the car is shaking like a mofo and i suspect a lost cylinder or something along the line.

I only thing i took off and touched was the throttle body, AAC and Air Reg so i can't understand why i would have these issues.

Anyone able to give me some advice?

Thanks.

hey guys,

after some investigating it seems engine/cylinder 6 is not running.

At first when i pulled out spark plug it was wet!

so i swapped over a new spark plug. It fixed it for like 30mins and then i had issues again.

this time i pulled out sparkie it was dry... i checked all other sparks and they are fine as well.

so i did the test where i pull the plug off each coil pack 1 by one and see if engine reacts.

all cylinders react except for #6!

i swapped the coil pack with #1 but its still the same.

so i can rule out spark plug and coil pack. i'm pretty sure i can rule out injector? as it made the spark plug wet the first time?

so what else could be the issue?

any advice on what else i can check would be great!

thanks.

If you have a multimeter, try probing a working cylinder to see what the normal output is to its coil plug, then try 6th coil plug and compare the 2, it might not be getting power/spark/whatever to it

      R34 GTR Speedo Drive , sensor type ?

      By Butters · Posted

      Working through possible solutions of converting my mechanical speedo.    Anyone know what type of speedo sensor the factory r34 gtr getrag has ? what the output is ? I assume its not a VSS and more a voltage like earlier speedo sensors ? Can an ECU read it ?

      I can get more photos of it here soon and I plan to make a thread detailing the process. I received the car this way and it sorely needs refinishing. That is probably the most appealing photo of it. Up close it is fading, cracked, and needs to be re-glued. Depending on their condition I'm on the fence between refinishing or making a new set.  Another angle hiding the pimples and razor pumps

      Can you mount the ATTESA pump in other locations?

      According to this thread the RS4V with build plate RC40 comes with the R200 diff @ 4.083 ratio as well (mine has said RC40 denotation). We may need to check if the axle stubs are the same pattern as well. The auto subframes have longer axles. However I think yours being a later Series 2 as well, we should have the same bolt pattern for the diff stubs. Unless your upgraded rear also has upgraded axles. Either way, I would not be opposed to pulling the covers to check so I can inspect that  fancy rear core  Also I don't have HICAS. I don't believe that should change things but I hope the people here with heaps more experience than me can correct me if I'm wrong   Let me know if you want to attempt to make this work and I can get some pictures of mine from under the car.

      It's not that straightforward. For example I have had this code because my ignitor/power transistor wires were unplugged. It knows something is wrong but has no idea what it means. If you want to actually diagnose this I recommend following the service manual flowchart for code 21. Ohm out the harness, coilpacks, inspect the ECU, etc. And again, it's entirely possible for there to be no problem at all but if you're running a different coilpack it'll trigger the code because it doesn't like what it sees.
