0'Im in a bit of a situation as well. I'm in SA and transported my 34 so it is still deregistered. Had to do a Vehicle Identity Inspection and I went through with adjustable coils. Had to get that engineered. 8 days after the inspection I took it to a shop. $1000 later took it back to the inspection centre. Had to book it in for a full roadworthy. Took it to my mechanic to fix a couple of things and to disconnect the turbo timer etc. Have the full roadworthy coming up soon. I have clear front and side indicators and have an exhaust other than that it's completely stock.

Yes, it only does it when I hold it in neutral, no matter the RPM's. I held it at 2300, 1500, 1800. I don't usually do it however I did notice and started to investigate! I'm taking it to a mechanic in the next couple of weeks so I'll ask him to have a look and see what he says!

I warm the engine up and it sits around 800 RPM. When I put my foot on the accelerator and the RPM's sit at lets say 2000 I can hear these little backfires from the exhaust. I've tested the engine pulling in 3rd and 4th gear from 3000RPM's and its fine so it's definitely not a misfire. The car has done 86,000kms and has been driven around 6,000kms since 2013. The engine is completely stock, except for the muffler. What could this be? Thanks!
