Hi all, been having idle problems for two years and finally found a fix the other day!

I had tried all the usual things like spark plugs, cleaning iac, cleaning maf, checking for vacuum leaks and everything you could imagine. But when changing my spark plugs again last week i noticed the coilpack springs had arcing marks on them.. so while driving it around for the week after changing plugs (still with the idle problem) i decided i would clean the bottom of the springs with some 400 grit and put some dielectric grease on the bottom of the spring and top of the spark plugs. PROBLEM SOLVED! My idle is now steady and i no longer get that rich smell from my exhaust..

For anyone that is wondering, the spring is just inside the rubber coil pack boot - it just pulls straight off.

    • Hi All, I'm based in Sydney and want to get hold of 4 stock R34 GTT wheel caps as pictured. Cheers
    • Haha im flattered! Although my poor boat is collecting dust in the garage, as it hasn’t been driven in like 6 months. I forgot the to put the trickle charger on too, so the battery is likely toast now.. I have the frenchys kit. It is fantastic. My only gripe was that the hard lines from the firewall needed some tweaking, however, this was mainly due to my specific turbo and dump combo. The weight and size packaging is much nicer too. I think I have some pics on my build thread somewhere.. my justification for the kit was more “why not” I had gone to the trouble to modernise just about every other part of the car..
    • Actually, ethanol has probably never been cheaper, on a tax free basis, than petrol. With fuel excise being what it is, and only being levied on the hydocarbon component, not the ethanol component, and ethanol for non-drinking purposes not being subject to liquor excise - E85 was cheaper, but not because the combustible liquid itself was particularly cheaper.
    • Maybe? If changing the cat to a higher flowing cat, caused the turbo to spool more quickly, and those areas of the map had not been tuned for the boost level it is now seeing, then yes you would need a re-tune. How dangerous it is running without the updated tune would depend on how far out the tune is with the now higher boost levels, how the engine protection has been setup, is the ECU compensating with a wideband sensor, is the boost control closed loop blah blah million other things... But yeah having said that, I wouldn't be surprised if changing out the cat for a high flow, in say a full 3" exhaust, made no noticeable difference at all. 
    • Ah yep. I asked a auto electrician about getting a cheap rebuilt alternator vs a new one. He also said he used to it back in the day but it ended up costing similar to what a new one would and recommended getting a new one,.
