Misfire + Idle --> Is Racing

[tripsteady]

Hi Guys

So ive searched and I can see that this topic has been beaten to death many times before , as the 7m's have gasket issues , the RB's seem to be prone to misfire and low revs

I bought my Skyline about 2 weeks ago , drives like a dream however when idling or waiting in traffic the revs seem to drop and the engine seems to misfire , the revs then pickup again but every now and then will drop and misfire.....

yes check AAC etc...but after i dropped 15k into my supra and worked on it by myself I promised not to touch a car(or at least my car) again...so im taking it to a professional.

Ive heard good things about Indy at IS Racing in Rockdale so i gave him a call , he seems to know a good deal about RB's

He then asked me what i petrol I use(told him premium 98) and then mentioned that RB's are known to drop revs and misfire from time to time because they are tuned for Japanese fuel but is now running on Australian fuel which is significantly different.

He said if im looking for silky smoothness (ie a "quiet engine , no taps etc) then i wont find this in an RB

I wanted him to take a look at it anyway so Im booked in at 11 tomorrow but just wanted to know what you guys thought of this....

Misfiring at low revs and revs dropping at idle because of the petrol we use is quite a big issue. My question is ,can any of you guys confirm this, is this a well known "RB fact"?

my car runs silky smooth and i run on e10....... (rb25det NEO @ 14psi stock turbo)

r33's have an issue with the aac getting really dirty and most people seem to flush them out or clean them.

i know of some people claiming to have problems in some of their skylines when running hi octane petrol, one guy says he has a perfectly stock r32gtr from japland and he has problems running 100octane and sais the car runs like shit and just spits and misfires, so he runs octane booster.

my 2 personal friends on the other hand, have both imported a r32gtr from japland 4 months ago, with everything stock besides the exhaust and the boost restrictor removed can run their cars perfectly on e10, 95oct,and 98oct.

so to be honest, i dont know what people have problems with.

checked ping. ive had no problems with pinging on e10. ethanol runs as good as it should. 95 i got more pinging than on e10.

why do people think e10 is shit petrol? we all know the properties of ethanol and the chemical structure. it is better than petrol
